Lesson Activities by Day

Date	Phase 1: Starter (7 mins) Preparing the brain	Phase 2: Main (29 mins) New learning + assessment	Resources	Phase 3: Plenary (9 mins) Reflection + exercise
Mon 16 Mar 2026	1Identify the key features that define fourth-generation computers. 2Ask learners to name any computer or device they use at home; write responses on board. 3Show picture of a laptop on projector and ask: What is inside that makes it work so fast?	FEATURES OF FOURTH-GENERATION COMPUTERS 1Display timeline on projector showing computer generations; learners read textbook page on fourth-generation features and write down 3 features (e.g. microchip, VLSI technology, affordable price). 2Pair learners to compare their 3 features and circle the common ones. 3A volunteer reads one feature aloud; class confirms by showing thumbs up. IDENTIFYING MICROCHIPS AND PROCESSOR ARCHITECTURE 4Show enlarged picture of a microchip on projector using Internet connection; ask: What do you see? What do you think it does? 5Learners sketch the microchip shape in exercise books and label 5 parts shown on the image. 6Ask a learner who finished early to explain to the class why a microchip is important in fourth-generation computers.	1Computer/Laptop 2Projector 3Textbook 4Internet connection	1Learners whisper one feature of fourth-generation computers to their partner and partner repeats it back. 2Show 3 pictures (older phone, smartphone, laptop) on projector; learners point to which is fourth-generation and why. Exercise 1Write one sentence: What is a microchip and why is it used in fourth-generation computers?
Tue 17 Mar 2026	1Demonstrate understanding of how input devices are used to enter data into a computer. 2Ask: What did you use to turn on your computer at home—a button, a switch, or voice? Write answers on board. 3Show 10-second video clip on projector of a barcode scanner being used at Makola Market checkout; ask learners to describe what they saw.	TYPES AND USES OF INPUT DEVICES 1Display 4 pictures on projector: wireless keyboard, wireless mouse, touchscreen, barcode scanner; learners read textbook section and match each picture to its use (e.g. typing, scanning, selecting, touching). 2Learners write the name and one use of each device in their exercise books. 3Ask one learner from each row to hold up their answer card. MANUAL AND AUTOMATIC INPUT DEVICES 4Draw two columns on board: 'Manual' and 'Automatic'; show 6 input device pictures on projector and ask learners to classify each by shouting 'Manual!' or 'Automatic!' for each one. 5Learners copy the two columns in their books and list 2 manual devices (keyboard, mouse) and 2 automatic devices (barcode scanner, touchscreen). 6Pairs compare their lists; any differences discussed with the teacher. ADVANTAGES AND REAL-WORLD APPLICATIONS 7Give scenario: Yakubu works as a trotro driver and wants to track passenger fares with a computer; which input device should he use? Learners write answer and reason. 8Ask a learner who chose barcode scanner to explain their thinking to the class. 9Learners find one more Ghanaian workplace (farm, market, hospital, school) and suggest an input device for that workplace.	1Computer/Laptop 2Projector 3Textbook 4Internet connection	1Learners show fingers 1–5 to rate their confidence in naming 5 input devices. 2Pairs quiz each other: One partner names a device, the other says if it is manual or automatic. Exercise 1List 3 input devices and write one advantage of each in a real Ghanaian workplace.
Wed 18 Mar 2026	1Examine the uses and features of output devices in real-world scenarios. 2Ask learners: When you watch a film on a projector in school, what device shows the picture? Write device names on board. 3Show 15-second video on projector of a graphing plotter drawing a map; ask: What is the machine doing and why?	TYPES AND APPLICATIONS OF OUTPUT DEVICES 1Display 4 pictures on projector: data projector, multimedia projector, pico projector, graphing plotter; learners read textbook and write what each device outputs (image, sound, data, graph). 2Learners match each device to a Ghanaian workplace: classroom (multimedia projector), small office (pico projector), technical drawing (plotter), cinema (projector). 3A volunteer from the group that finished first presents one match to the class. COMPARING OUTPUT DEVICES: ADVANTAGES AND DISADVANTAGES 4Create comparison table on board with 3 rows (Projector, Plotter, Pico Projector) and 2 columns (Advantage, Disadvantage); learners copy and complete using textbook examples. 5Learners evaluate: Which output device is best for Ama's small tailoring shop for displaying designs? Learners write their choice with 1 reason. 6Ask learners who chose different devices to respectfully debate why their choice is better. REAL-WORLD USES AND PROBLEM-SOLVING 7Scenario: A school principal needs to show exam results to 200 learners in the hall; which output device fits best? Learners discuss in pairs and write 1 sentence answer. 8Extension: Design a Ghanaian business (e.g. graphics design studio, hospital, engineering firm) and choose 2 output devices it needs; learners sketch and label. 9Ask a learner who struggled with the starter to attempt this scenario first with teacher support.	1Computer/Laptop 2Projector 3Textbook 4Internet connection	1Learners repeat chorally 3 times: 'Projectors output light, plotters output drawings, all output devices show computer data.' 2Thumbs up if you can name 3 output devices; thumbs sideways if you can name 2; thumbs down if you need more practice. Exercise 1Name 2 output devices and explain 1 advantage and 1 disadvantage of each in a workplace you know in Ghana.
