- 1Learners will recall and identify examples of computer networks they encounter daily in Ghana and explain why computers need to connect to each other. This objective is critical because learners must understand the PURPOSE of networking (sharing data, sending messages, accessing shared resources) before they can understand HOW different topologies organise these connections
- 2Activity 1 — Activation of Prior Knowledge: Ask learners: 'When you visit an internet café or your school office, what devices do you see connected together? Show your hand if you have used a computer that was connected to a printer.' Allow 3–4 learners to respond with names of devices. Then ask: 'Why do you think we connect computers instead of keeping them separate?' Guide them to realise that connection allows sharing of files, printers, and internet. This prepares their minds for the concept that different WAYS of connecting (topologies) exist
|
- UNDERSTANDING WHAT NETWORK TOPOLOGIES ARE AND WHY THEY MATTER
- 1Main Activity — Definition and Purpose of Topology: Write on the board: 'NETWORK TOPOLOGY = The pattern or SHAPE that shows how computers and devices are connected together.' Say to learners: 'Just like houses in a village can be arranged in a line, a circle, or scattered around, computers in a network can be arranged in different shapes. Each shape is called a TOPOLOGY. Today we look at four main topologies used around the world.' Ask: 'Can anyone guess what we might call a topology where computers are in a straight line like a queue at a bus stop?' Accept guesses. Reveal: 'That shape is called BUS TOPOLOGY.' Repeat this discovery approach for the other three names (Star, Ring, Mesh) by asking guiding questions. Write all four names on the board and keep them visible throughout the lesson. Teacher note: This approach helps learners construct meaning rather than simply memorise definitions
- 2Sub-Activity 1 — Guided Drawing of Topology Names: Give learners A4 paper and coloured pencils. Say: 'We are going to draw four simple boxes on your paper—one for each topology name. In each box, write the NAME of the topology (BUS, STAR, RING, MESH). Leave space below each name for a diagram we will draw in the next activity.' Circulate and check that all learners write the four names correctly. This builds a template they will use throughout the lesson
- 3Sub-Activity 2 — Classroom Discussion on Why Topologies Matter: Ask: 'Why do you think different topologies exist? Is one way of connecting computers better than all the others?' Guide learners to understand that different businesses need different topologies. Say: 'A small internet café might use one topology, but a big bank needs a different topology because it has many more computers.' Ask: 'Who has seen a bank or an office? Do you think all the computers inside are connected the same way or different ways?' This plants the idea that topology choice depends on the SIZE and PURPOSE of the network. Differentiation note: Struggling learners may need the four names repeated 3–4 times. Write each name in a different colour and ask them to point to it when you say it aloud. Fast finishers can research one real-world building (school, market, hospital) and decide which topology might be used there—they will share this guess at the end of the lesson
- 4Teacher support: You are introducing an abstract concept (topology). Use the concrete examples (queue at bus stop, star shape, circle, interconnected web) to make it visible. Avoid technical jargon beyond what is written. Learners at this stage (B7) should see topology as 'the SHAPE of connection,' not as complex network engineering. Keep the board organised with the four names in a clear list. Differentiation: Struggling learners benefit from coloured visual labels and repeated oral exposure. Average learners work through the four-box template with teacher guidance. Fast finishers extend by researching real-world applications—this challenges their thinking at the Analyse level (Bloom's).
- DRAWING AND DESCRIBING THE FOUR NETWORK TOPOLOGIES USING DIAGRAMS
- 5Main Activity — Step-by-Step Diagram of BUS Topology: Say: 'BUS topology looks like a straight LINE of computers connected by ONE cable that runs from one end to the other—like a water pipe with computers attached to it.' On the board, draw a horizontal straight line. Mark five dots on the line (representing computers/nodes). Label them: Computer 1, Computer 2, Computer 3, Computer 4, Computer 5. Write a label: 'All computers connect to ONE MAIN CABLE.' Ask learners: 'If Computer 1 sends a message, where does it go? Does it go straight to Computer 5 or does it travel along the main cable?' Guide them to say 'along the main cable.' Say: 'Correct! In BUS topology, all messages travel on the same cable.' Now have learners draw this BUS diagram in their first box on their A4 paper. Provide a laminated reference card or display the diagram on the wall for them to copy. Circulate and correct any learner who draws more than one cable or places computers off the line. Say: 'Now label YOUR diagram with the sentence: All computers are connected to ONE main cable.' Teacher content note: BUS topology is the simplest. In real networks (old computer lab setups, some small offices), a single coaxial cable runs through the room and each computer taps into it. The weakness is that if the cable breaks, the whole network stops. Point this out after learners draw it: 'What happens if this cable is cut? All five computers cannot talk anymore.'
- 6Sub-Activity 1 — Drawing STAR and RING Topologies: Say: 'Now let's draw STAR topology.' On the board, draw a central square (the hub or switch) and draw five circles around it in a star pattern, with lines connecting each circle to the center. Say: 'In STAR topology, there is ONE central device in the middle—we call it a HUB or SWITCH. Every computer connects ONLY to this hub, not to each other. Look—it looks like a STAR!' Ask: 'How is this different from BUS?' Guide learners to see that here there is a center device, not a main cable. Have learners draw STAR in their second box and label it: 'All computers connect to a CENTRAL HUB.' Then draw RING topology: a circle of five nodes with lines forming a ring. Say: 'RING topology looks like a circle or a ring on your finger. Each computer connects to exactly TWO others—the one before it and the one after it. Messages travel AROUND the ring.' Learners draw RING in their third box and label: 'Computers are arranged in a circle, each connects to two others.' Teacher content note: Emphasise the VISUAL difference. BUS = LINE, STAR = hub with spokes, RING = circle. Use these words every time. Differentiation: Struggling learners use templates—provide pre-drawn outlines they only need to label. Average learners draw from your board diagram. Fast finishers draw STAR and RING in different colours and list one advantage and one disadvantage of each based on what you have said (e.g. STAR advantage: if one computer fails, others still work; disadvantage: if hub fails, all fail)
- 7Sub-Activity 2 — Drawing MESH Topology and Comparing All Four: Say: 'The last topology is MESH. In MESH topology, computers are FULLY CONNECTED—every computer connects to EVERY other computer!' On the board, draw five circles and draw lines connecting EVERY circle to EVERY other circle. It will look very complex and tangled. Say: 'This is why we call it MESH—it looks like a mesh fishing net with connections everywhere!' Ask: 'Do you think this topology uses more cables or fewer cables than BUS?' Guide learners to say 'many more cables!' Say: 'MESH is very expensive and complicated, but it is also very STRONG—if one computer or cable breaks, messages can still travel on other paths.' Have learners draw MESH in their fourth box and label: 'Every computer connects to every other computer—many cables needed.' Now hold up all four diagrams (on laminated cards or displayed on the wall). Ask: 'Which topology uses the LEAST cables?' (BUS). 'Which topology is the SAFEST if cables break?' (MESH). 'Which topology has a center device?' (STAR). 'Which topology looks like a circle?' (RING). Learners answer by holding up fingers 1–4 to show which box on their paper each question refers to. Differentiation: Struggling learners may find MESH confusing because of the many lines. Simplify by saying: 'MESH means EVERY computer talks to EVERY other computer directly—imagine every friend in your class has your phone number AND you have everyone's number.' Fast finishers draw a PARTIAL MESH (where not every computer connects to every other) and explain how it balances cost and safety
- 8Teacher support: This is the CORE of the lesson. Learners MUST be able to draw and name the four topologies. Use the Computer/Laptop to display clear, large diagrams of each topology if available (search 'network topology diagrams' on the school's device). Alternatively, draw them clearly on the board step-by-step, talking through each line. Do NOT rush this section. Spend 3–4 minutes on each topology. Differentiation: Provide struggling learners with pre-drawn templates (outlines of each topology) so they only need to label and colour. Average learners draw from the board with your step-by-step guidance. Fast finishers extend by researching which topology their school uses (hint: schools often use STAR because it is reliable) and present one sentence at plenary. Use coloured chalk or whiteboard markers for each topology so visual memory is reinforced. Write a KEY on the board: BUS (line) | STAR (hub) | RING (circle) | MESH (all connected). Point to this key repeatedly as you teach.

- 1Computer or Laptop (to display network topology diagrams as reference, optional but helpful)
- 2A4 paper (one per learner)
- 3Coloured pencils or crayons (5–6 per learner)
- 4Whiteboard and markers (or chalkboard and chalk)
- 5Laminated reference cards showing the four topologies (teacher-made or printed before lesson)
- 6Ruler (for drawing straight lines in BUS and RING topologies)
|
- 1Plenary Activity 1 — Quick Recall Challenge Using Hand Signals: Say: 'I will describe a topology. You show me with your hands the SHAPE.' Then give clues: (1) 'All computers are in a straight LINE connected by ONE cable. Show me a LINE with your finger.' Learners draw a line in the air. Say: 'That is BUS topology!' (2) 'One device in the MIDDLE and computers around it like a STAR. Show me!' Learners spread their fingers in a star shape. Say: 'That is STAR topology!' (3) 'Computers form a CIRCLE, each talks to the two next to it. Show me!' Learners join hands in a circle or make a circle shape. Say: 'That is RING topology!' (4) 'Every computer is CONNECTED to every other computer—very tangled like a fishing net. Show me a tangled mesh!' Learners wiggle all their fingers together. Say: 'That is MESH topology!' This activity consolidates the four names and their shapes through physical movement and visual recall. Repeat once more, going faster. Ask learners to whisper the name of the topology as they show the shape
- 2Plenary Activity 2 — Real-World Application Discussion: Say: 'Let's think about Kwame's internet café in Accra with 10 computers. Which topology should Kwame choose and WHY?' Invite a learner who has been engaged to answer. Guide the discussion: 'STAR is a good choice because if one computer breaks, the others still work. BUS is cheap but risky. MESH is too expensive.' Ask: 'What about a large bank with 200 computers? Would MESH be good?' Guide learners to think about cost and safety trade-offs. Ask: 'Has anyone seen cables behind computers at school or at home? Can you describe how they were arranged?' Accept real observations. This consolidation links the abstract diagrams to the real world they live in. Ask: 'Why did we learn about topologies today?' Guide learners to say: 'So we understand how computers are connected' and 'So we can choose the best way to connect computers for different situations.'
Exercise
- 1Written Assessment Exercise: Give each learner a blank piece of paper. Write on the board: 'DRAW A DIAGRAM of STAR TOPOLOGY. Label the central device as HUB. Draw four computers around it and draw lines from each computer to the HUB. Write one sentence explaining: Why is STAR topology good for a school computer lab?' Learners complete this individually. Model answer hint: Diagram should show a central rectangle or circle labeled HUB with four circles around it and lines connecting each circle to the center. The sentence should contain: 'If one computer breaks, the others still work' OR 'It is reliable because there is a central device managing the connections' OR 'The hub controls communication, so it is organized.' Collect these exercise papers at the end of the lesson to assess whether learners have met the day's indicator: identifying and drawing a network topology with accuracy. Use this to inform Day 2 planning—if most learners struggle with STAR, spend extra time on RING and MESH review before introducing new content in their exercise books.

- 1Learners will identify and name the four main types of network topologies (Bus, Star, Ring, Mesh) by examining real-world network examples. This objective is critical because understanding topology types helps learners recognise how computers connect in schools, offices, and businesses across Ghana—preparing them to design and troubleshoot networks
- 2Activity 1 — Quick Network Hunt: Display four simple unlabelled diagrams on the laptop screen (one Bus, one Star, one Ring, one Mesh topology). Ask learners: 'Look at these four diagrams. What do you notice about how the dots (computers) are connected to each other?' Call on learners to describe what they see (e.g. 'In this one, all computers are on one line' or 'This one has a computer in the middle'). Do NOT name the topologies yet—just activate their observation skills. Learners whisper their observations to a partner first, then volunteer responses to the whole class
|
- UNDERSTANDING AND DRAWING THE FOUR NETWORK TOPOLOGIES
- 1Main Activity — Guided Diagram Construction Using the Laptop: Open MS-Paint or a simple drawing programme on the laptop and connect it to a projector or display screen so all 30 learners can see. Say: 'I am going to draw four network topologies step by step. You will draw the same diagrams in your exercise books.' Draw the diagrams on the laptop in this order: (1) BUS TOPOLOGY: Draw a horizontal line. Label it 'Main Cable'. Draw 5 circles (nodes/computers) along the line. Label them: 'Computer A, Computer B, Computer C, Computer D, Computer E'. Ask: 'How many cables connect the computers?' (Answer: one main cable). Write on the board: 'BUS: All computers on ONE main cable.' (2) STAR TOPOLOGY: Draw a circle in the middle. Label it 'Switch (central device)'. Draw 5 circles around it. Label them: 'Computer 1, Computer 2, Computer 3, Computer 4, Computer 5'. Draw lines from each computer to the switch. Ask: 'Which computer or device is in the middle controlling everything?' (Answer: the Switch). Write: 'STAR: ONE central device. All computers connect to IT.' (3) RING TOPOLOGY: Draw 5 circles in a circle shape. Label them: 'PC1, PC2, PC3, PC4, PC5'. Draw lines connecting them in a circle (PC1→PC2→PC3→PC4→PC5→PC1). Ask: 'How is this different from the Star?' (It has no centre; data goes round and round). Write: 'RING: Computers form a CIRCLE. Data moves round like a circle game.' (4) MESH TOPOLOGY: Draw 5 circles scattered. Draw lines connecting EVERY circle to EVERY other circle (show a complex web of lines). Ask: 'How many cables does a Mesh need?' (Many—every computer talks to every other computer). Write: 'MESH: EVERY computer connects to EVERY other computer. Very strong but expensive.' As you draw each topology on the laptop, ask learners to copy the exact same diagram into their exercise books. Call on volunteers to come to the board and label each diagram
- 2Sub-Activity 1 — Labelling and Feature Identification: Give learners a worksheet (printed or written on the board) with four blank topology diagrams. Learners label each diagram with: (a) the topology name, (b) the number of connections/cables needed, (c) one advantage (write on the board: BUS=simple, STAR=reliable, RING=fair, MESH=very safe). Learners work individually. Select a learner who finished early to read out their labels to the class. Check answers on the board together. This activity builds understanding (Bloom's Understand level) by requiring learners to describe and classify each topology
- 3Sub-Activity 2 — Pair Comparison Task: Pair learners (15 pairs from 30 learners). Give each pair a comparison chart on the board or handout with rows: 'Topology Name | Number of Cables Needed | Ease of Use | Cost | Best For'. Pairs complete rows for two topologies they choose (e.g. Star and Mesh, or Bus and Ring). After, ask one representative from each pair to share one row. Write answers on the board. Learners copy the completed chart into their books. This builds analysis skills (Bloom's Analyse level) by asking learners to differentiate between topologies
- 4Differentiation: Struggling learners — provide a partially completed diagram template with topology names already written. They only add labels for devices and cables. Pair them with a stronger learner during Sub-Activity 2. Average learners — complete the full tasks as described. Fast finishers — after 5 minutes, ask them to design a FIFTH topology called 'HYBRID' that combines features of two topologies they choose (e.g. 'We connect three Star topologies together with a Ring'). Have them draw and present this to the class in the plenary. TLR use: The laptop and display screen are used throughout to model exact diagram construction, ensuring all learners see clear examples before drawing.

- 2Projector or display screen
- 3Whiteboard and markers
- 4Exercise books and pencils
- 5Printed worksheet with blank topology diagrams (or write on board)
- 6Comparison chart handout or board copy
|
- 1Plenary Activity 1 — Topology Matching Game: Display one topology diagram on the laptop at a time (no label). Ask the whole class: 'What is this topology called? Show your answer by holding up fingers: 1 for Bus, 2 for Star, 3 for Ring, 4 for Mesh.' Learners hold up fingers silently. Ask: 'Who chose 2 (Star)? Tell the class one reason why this is a Star topology.' Call on three learners to justify their answers. This consolidates recognition and naming of each topology through peer explanation
- 2Plenary Activity 2 — Real-World Application Reflection: Ask learners: 'In Kofi's school computer lab in Kumasi, there are 10 computers and 1 printer. Which topology would Kofi's IT teacher use? Why?' Learners whisper their answer to a partner first (likely answer: Star, because the printer can be the central device). Ask three pairs to share aloud and explain. Say: 'You have now learned how computers connect in different ways. Tomorrow we will learn how data travels through these networks.' This links today's learning to tomorrow's lesson and shows real-world relevance
Exercise
- 1Learners complete this assessment question in their exercise books (write on the board): 'Draw and label a Star topology with 4 computers and 1 switch in the centre. Then write two sentences explaining why a school would choose a Star topology instead of a Bus topology.' Model answer hint: Diagram shows switch in centre with four computers connected by lines. Explanation mentions: 'Star is reliable because if one cable breaks, only one computer is affected, not all. Star is easy to add new computers.' This directly assesses the Phase 1 objective (identifying and naming topologies) at the Apply level (drawing and explaining)
|
|
|
- 1Learners will recall the names and key features of four computer network topologies (Bus, Star, Ring, Mesh) from previous lessons. This objective builds confidence and activates prior knowledge before moving to the main drawing task, ensuring learners have secure foundation concepts before representing topologies visually
- 2Show learners three simple line drawings (unlabelled) of different network layouts on the board or printed handout: one showing computers in a straight line, one showing computers arranged around a central point, and one showing computers in a circle. Ask: 'Which of these arrangements have you seen before? What was each one called?' Invite volunteers to name the topologies and point to the key feature in each (the straight line, the central hub, the circular chain). Record their answers on the board as you confirm correct names: Bus, Star, and Ring
|
- UNDERSTANDING AND IDENTIFYING TOPOLOGY FEATURES IN PRINTED DIAGRAMS
- 1Display four printed or projected reference diagrams (one for each topology: Bus, Star, Ring, Mesh) on the Computer/Laptop screen or on A3 printed posters around the classroom. Point to each one and explain using exact language: 'Bus topology: all computers connect to ONE long cable running in a straight line from computer to computer. Star topology: all computers connect to ONE central device (called a hub or switch) — like spokes on a bicycle wheel. Ring topology: computers connect in a circle — each one connects to exactly TWO others. Mesh topology: every computer connects to EVERY other computer — many cables, but very reliable.' Write these four headings on the board. Ask learners: 'Which topology has the most cables? Which has the fewest?' (Mesh has most, Bus has fewest.) This establishes understanding of structural differences
- 2Distribute a printed worksheet showing four unlabelled network diagrams (one Bus, one Star, one Ring, one Mesh). Learners work in pairs to identify each topology and write its name on a label. They must also write ONE feature that helped them identify it (e.g. 'Star — all cables meet at the centre'). Circulate and check understanding. Ask guiding questions: 'How many computers does this one connect to a central hub?' or 'Are the computers in a line or a circle?' This consolidates visual recognition before drawing
- 3Ask learners: 'If Ama works in a school computer lab where one cable runs from computer to computer in a line, what topology is the school using?' (Answer: Bus.) 'If Kwame's internet café has all computers plugged into one central switch on the wall, what is that?' (Answer: Star.) Use these Ghanaian context questions to check comprehension and build confidence for the drawing phase
- 4Struggling learners: Provide a completed labelled diagram card for each topology that they can keep beside them during the practice task. Fast finishers: Ask them to predict which topology would be best for a Makola Market trader network with 20 computers and to explain why in one sentence.
|
- 1Computer/Laptop with projector or screen
- 2Printed reference diagrams (Bus, Star, Ring, Mesh topologies) — A3 size or projected
- 3Printed identification worksheet with four unlabelled diagrams
- 4Small printed cards with topology names (Bus, Star, Ring, Mesh) — one per pair
- 5Blank A5 cards or half-page sheets for the final exercise
- 6Marker pens and rulers (for drawing straight lines)
|
- 1Display a partially drawn topology diagram on the Computer/Laptop projected on screen (e.g. a Star topology with the hub drawn but only 3 of 5 computers connected). Ask the class: 'What is missing? How many more computers should connect to this hub?' Call on a learner who has not yet contributed to come to the board or screen and add the missing connections using a pointer or stylus. Ask the whole class: 'Does this now show a complete Star topology? How do you know?' Learners respond chorally: 'Yes — all computers connect to one central hub.' This reinforces the exact structure of each topology
- 2Ask learners to stand and mime the topology you call out. Say: 'Bus!' — learners stand in a straight line, shoulder to shoulder, representing the single cable. Say: 'Star!' — learners form a circle with one volunteer in the centre as the hub, others around the edge representing nodes. Say: 'Ring!' — learners hold hands in a circle, each person connecting to two neighbours. This kinaesthetic activity consolidates understanding in a memorable way and allows you to observe which learners understand the spatial arrangement of each topology
Exercise
- 1On a blank A5 card or half-page, learners will draw and label ONE network topology of their choice (Bus, Star, Ring, or Mesh). They must: (1) draw the topology clearly, (2) label at least four nodes (computers), (3) show connecting cables or lines, and (4) write the topology name at the bottom. Model answer: A Star topology showing one central hub with four computers arranged around it, each connected by a line to the hub, labelled 'Star Topology.' Success = correct topology structure with all parts labelled. This directly assesses the Phase 1 objective of naming and identifying topologies, plus begins the drawing skill required by the lesson indicator in their exercise books.

- 1Identify the concept of computer networking for global communications and recall examples of networks in Ghanaian environments. This objective matters because learners must understand the foundational value of networks before they can explore business opportunities and entrepreneurial applications
- 2Activity 1 — Network Recall Task: Display three images on the board (or describe verbally): a school computer lab, a bank's ATM network, and a hospital's patient records system. Ask learners: 'What do you think these places have in common?' (Expected answer: they all use connected computers). Ask follow-up: 'Have you seen computers connected together in your school, church, or local market?' Learners whisper their answer to a partner, then one volunteer shares aloud. Teacher confirms that these are examples of computer networks
|
- ENTREPRENEURIAL OPPORTUNITIES IN NETWORKING COMPUTING DEVICES
- 1Main Activity — Network Infrastructure Business Case Study: Display or read aloud this scenario on your computer/laptop (using the Computer as a TLR): 'Kwame is a young entrepreneur in Tema. He noticed that three schools in his area have no computer networks. Teachers cannot share resources, and students cannot access the internet for research. Kwame decides to install a network system in these schools, charging GH₵500 per school per month for maintenance.' On the board, write three columns: OPPORTUNITY | WHAT IT SOLVES | WHO BENEFITS. Under OPPORTUNITY, write: 'Network Installation & Maintenance Service'. Ask learners: 'What problem does Kwame solve? (Teachers and students cannot share resources or access the internet.) Who benefits? (Schools, teachers, students, Kwame himself.) How does this connect to global communications? (Students can now access websites and collaborate online with students worldwide.)' Ask a learner who found the starter easy to explain why Kwame's business is valuable. Teacher explains: networking devices is an entrepreneurial opportunity because businesses, schools, and hospitals will pay for someone to set up, manage, and maintain their networks
- 2Sub-Activity 1 — Three-Environment Application Task: Give learners a sheet with three headings: SCHOOL | BUSINESS | HEALTH. Under each heading, write one scenario. SCHOOL: 'Ms. Abena is a headmistress at a school in Ho. She wants all classrooms to share internet and printers.' BUSINESS: 'Yaw owns a transport company with 20 trotros. He wants drivers to upload daily reports and passengers to book seats online.' HEALTH: 'Dr. Akua runs a clinic in Bolgatanga. She wants to send patient records securely to the regional hospital for specialist advice.' Ask learners (in pairs): 'For each scenario, what network service would you provide as an entrepreneur? Write your answer.' Circulate and listen to pair discussions. Ask one pair from the front to read their answer for the school scenario aloud. Teacher confirms and adds: 'You could charge the school a monthly fee to install Wi-Fi, train staff, and fix problems.'
- 3Sub-Activity 2 — Challenges & Solutions Debate: Write on the board: 'CHALLENGE: Networks are expensive to set up. How can an entrepreneur overcome this?' Divide the class into two groups (by counting 1–2 around the room). Group 1 argues: 'Offer payment plans — schools pay in three instalments.' Group 2 argues: 'Partner with the government — get subsidies for rural clinics.' Give each group to prepare. A representative from each group speaks ( each). Teacher summarises: 'Smart entrepreneurs find creative ways to manage costs, making networking affordable for more people.' This shows learners that entrepreneurship requires both technical knowledge and business thinking
- 4Struggling learners: Pair them with stronger peers during the three-environment task. Provide sentence starters: 'The school needs ___ so they can ___.' Average learners: Complete the task as described. Fast finishers: Create a fourth scenario (transport, education, agriculture) and propose a complete network solution with a price. Invite one fast finisher to present their scenario to the class before plenary.

- 1Computer/Laptop (for displaying scenarios and questions)
- 2Chalkboard or whiteboard with markers
- 3Exercise books and pens
- 4Optional: printed scenario cards for three-environment task
|
- 1Plenary Activity 1 — Global Communications Link: Ask the whole class: 'We talked about networks in Ghana — Makola Market, schools in Ho, clinics in Bolgatanga. But how do all these networks connect to the world?' Write 'GLOBAL COMMUNICATIONS' on the board. Explain: 'When Ama sends money via MoMo, it travels through mobile networks to banks in Accra and beyond. When a student in a networked school watches a YouTube video, they connect to servers in America or Europe. Networks make Ghana part of the global system.' Ask learners: 'Can you think of one way that a networked device in Ghana talks to someone outside Ghana?' (Expected: social media, email, online shopping, international calls). A volunteer shares. Teacher affirms and adds: 'This is why entrepreneurs who build networks are valuable — they connect Ghana to the world.'
- 2Plenary Activity 2 — Entrepreneurship Reflection Pair-Share: Ask learners to turn to a partner and discuss: 'If you were an entrepreneur, which type of network business would you start — in a school, a business, or a health facility? Why?' Learners whisper their choice and reason to their partner. Alternate between boys and girls: call on a boy to share his choice, then a girl to share hers. Teacher listens, affirms each response ('That's a good business idea because.'), and thanks them. Summarise: 'Network entrepreneurs solve real problems. They help schools teach better, businesses work faster, and hospitals save lives. That's why networking is not just technical — it's about making Ghana and the world better.'
Exercise
- 1Written Exercise — Entrepreneurial Opportunity Identification: Display this question on your laptop or write on the board: 'Kofi is a young man in Kumasi. He sees that five market traders (like those at Kejetia Market) do not have internet to check prices of goods from suppliers in Accra. Write a short paragraph (5–7 sentences) describing how Kofi could start a networking business to help these traders. Include: (1) What network service would he provide? (2) How much might he charge? (3) Who would benefit? (4) How does this help global communications?' Model Answer Hint: A strong answer includes: 'Kofi could install Wi-Fi and a shared computer system so traders can check online prices. He might charge GH₵50 per trader per month. Traders benefit because they know fair prices; Kofi benefits from fees. This helps global communications because traders in Kumasi connect to suppliers and buyers worldwide, making Ghanaian trade stronger.' Learners write in exercise books. Collect books or check 5–6 responses to assess understanding of both the entrepreneurial concept and the global communications link
