- 1Learners will recall and identify everyday examples of rotation and describe the direction of rotational movement (clockwise or anti-clockwise). This objective is critical because rotation is a foundation transformation concept in geometry; learners must first recognise rotation in their lived environment before they can perform it mathematically on shapes
- 2Activity 1 — Spinning Clock Scenario: Show learners an analog clock face or draw one on the board. Ask: 'When Ama looks at her clock in Makola Market at 3 o'clock, which way do the hands move — left or right?' Pause for responses. Then ask: 'If the hand moves from 12 to 3, is that clockwise or anti-clockwise?' Learners discuss with their partner and raise hands. Confirm the direction aloud together

- UNDERSTANDING ROTATION: REAL-LIFE EXAMPLES AND DIRECTION TERMINOLOGY
- 1Main Activity — Identifying Rotation in Everyday Objects: Write on the board: 'A fan spinning. A door opening. A football rolling. The sun moving across the sky.' Read each scenario aloud. Ask learners: 'Which of these show rotation (turning around a fixed point)?' Discuss each one. Guide them to understand that rotation means turning around a central point, and that rolling is NOT pure rotation. Use the ruler and graph board to draw a simple diagram of a fan blade at a fixed centre point, with an arrow showing the turning direction. Explain: 'The blade rotates around this centre point. See the arrow? That shows the direction.' Ask: 'Does the arrow go the same way as a clock hand, or the other way?' Learners answer chorally
- 2Sub-activity 1 — Classifying Clockwise and Anti-Clockwise Movement: On the manila card, draw two large arrows in opposite directions (one clockwise, one anti-clockwise). Label them clearly: 'CLOCKWISE' and 'ANTI-CLOCKWISE'. Hold the card up. Ask: 'If this arrow (point to clockwise) is how a clock moves, which direction is that called?' Repeat for anti-clockwise. Now give learners five verbal scenarios: (1) A door swinging open from left to right. (2) A spinning top turning left. (3) A steering wheel turning to make a right turn. (4) A ceiling fan in a bedroom. (5) A merry-go-round at the fairground. For each, ask: 'Clockwise or anti-clockwise?' Learners hold up one finger (clockwise) or two fingers (anti-clockwise). Use this to gauge understanding and correct misconceptions immediately
- 3Sub-activity 2 — Marking Rotation on the Graph Board: Distribute the exercise books and rulers. Draw a simple square on the graph board (using the ruler to show straight edges). Mark a point at the centre of the square with a dot (the centre of rotation). Now draw an arrow showing the square rotating 90° clockwise around that centre point. Ask: 'See the arrow? It shows the direction the square is turning. Is it going clockwise or anti-clockwise?' Learners write 'Clockwise' in their exercise books. Repeat with a second example: a triangle rotating anti-clockwise. Learners must identify the direction and write it down. Circulate and check their answers
- 4Differentiation: STRUGGLING LEARNERS — Provide a physical clock or use a digital clock on your phone. Let them trace the movement with their finger three times before answering questions. Use only clockwise examples first, then introduce anti-clockwise once they are confident. AVERAGE LEARNERS — Use the scenarios above as written. FAST FINISHERS — Ask them to find THREE objects in the classroom (e.g. a fan, a door, a light switch) and determine if each rotates clockwise or anti-clockwise. They sketch these in their exercise books with direction arrows and explain to a peer.

- 1Plenary Activity 1 — Rotation Direction Gallery Walk: Display the two manila cards (clockwise and anti-clockwise labels) on opposite walls of the classroom. Read five rotation scenarios aloud. For each one, learners walk to the wall that shows the correct direction. Examples: (1) A wheel on a bicycle moving forward. (2) A door opening away from you. (3) The hands of a watch. (4) A spinning top turning to the left. (5) A steering wheel turning left. As learners move, observe their choices and use this to confirm their understanding. Ask the group standing at the correct location to explain their choice to the class
- 2Plenary Activity 2 — Partner Explanation: Learners pair up (sitting next to each other). One learner explains to their partner: 'What is rotation, and what are the two directions it can go?' Their partner listens and asks one clarification question. Then they switch roles. Invite two pairs to share their explanation with the whole class. Listen for correct use of 'clockwise', 'anti-clockwise', and 'turning around a fixed point'. Affirm correct language use
Exercise
- 1Exercise (Written Assessment): In your exercise book, draw a simple circle. Mark a dot at the centre. Draw an arrow showing a clockwise rotation. Below your drawing, write one sentence: 'Name a real-life object that rotates clockwise.' Model answer hint: Learners should draw a circle with a marked centre point, show an arrow pointing in the clockwise direction (same way as clock hands move), and name an object such as: a clock, a ceiling fan, a merry-go-round, a steering wheel turning right, or a spinning plate. Accept any real-world example that actually rotates clockwise

- 1Learners will recall the properties of rotation transformations and identify the direction and angle of rotation for shapes plotted on coordinate planes. This objective is critical because learners must activate their prior knowledge of rotation (learned on Day 1) before applying complex rotation tasks in a coordinate system today
- 2Quick Recall Task — Show learners a printed image of a triangle shape rotated 90° clockwise from its original position (on the board or on a manila card). Ask: What transformation has happened to this triangle? Can you name the direction it has turned? Is it a clockwise or anti-clockwise rotation? Encourage learners to discuss with their neighbours and raise their hands. This primes their memory of rotation vocabulary

- PLOTTING AND ROTATING SHAPES ON A COORDINATE PLANE — CLOCKWISE ROTATIONS
- 1Main Activity — Guided Plotting and 90° Clockwise Rotation. Explain to learners: Today we apply rotation rules on a coordinate plane using a ruler and graph board. Learners open their exercise books and draw a coordinate plane with axes from −4 to 4 on both x and y axes using a ruler (TLR). Write on the board: Original shape: Point A(1,2), Point B(3,2), Point C(3,0). Ask learners to plot these three points on their graph boards and join them to form a right triangle. Then say: We will rotate this triangle 90° clockwise about the origin. Write the rotation rule on the board: (x, y) → (y, −x). Demonstrate on a large drawn coordinate plane on the board or on a manila card: Point A(1,2) becomes A'(2,−1). Ask learners to apply this rule to points B and C. Circulate and check three learners' working as they plot. Ask: What shape have we made with the new points? (This should be a triangle again, but rotated.) Have learners draw the rotated triangle A'B'C' on their graph boards using a ruler
- 2Sub-Activity 1 — Peer Checking of Rotation Points. Ask learners to exchange their exercise books with the person sitting next to them. Provide a simple checklist on the board: Does point A' lie at (2, −1)? Does point B' lie at (2, −3)? Does point C' lie at (0, −3)? Learners tick off the checklist as they check their partner's work. This builds collaborative learning and catches errors early
- 3Sub-Activity 2 — Anti-Clockwise Rotation Application (Extension). For learners who completed the clockwise task accurately, provide the extension: Now rotate the original triangle A(1,2), B(3,2), C(3,0) by 90° anti-clockwise about the origin. The rule is: (x, y) → (−y, x). Write this rule on the board. Ask these learners to apply it to all three points and plot the new triangle A''B''C'' on their graph boards using their ruler. Invite a fast finisher to come to the board and show one transformed point to the class. This challenges advanced learners and reinforces understanding of both rotations
- 4Differentiation: Struggling learners — Provide a pre-drawn coordinate plane on a printed worksheet so they focus only on applying the rotation rule and plotting. Work through the first point (A to A') with them step-by-step before they attempt B and C independently. Average learners — Follow the main activity as described; circulate to check each learner plots at least two points correctly before moving on. Fast finishers — After completing the 90° clockwise task, challenge them to predict and draw a 180° rotation of the same triangle without the rule written out, then verify their answer using the rule (x, y) → (−x, −y). This builds critical thinking.

- 1Whole-Class Consolidation — Draw a Summary Table on the Board. Create a simple table with three columns: Rotation Direction | Rule | Example. Fill in: Clockwise 90° | (x, y) → (y, −x) | (2, 3) → (3, −2). Clockwise 180° | (x, y) → (−x, −y) | (2, 3) → (−2, −3). Clockwise 270° | (x, y) → (−y, x) | (2, 3) → (−3, 2). Point to each row and ask learners to repeat the rule chorally three times. Then ask: Why does the rule change when we rotate in different directions? Accept responses that mention the x and y coordinates swap or change sign. This reinforces the pattern and consolidates all three key rotation angles
- 2Peer Reflection and Angle Determination Task — Show learners a drawn shape on a large coordinate plane (manila card or board). Tell them: A triangle with corners at A(1,1), B(2,3), C(4,1) has been rotated to A'(−1,1), B'(−3,2), C'(−1,4). Work with your partner to determine: What angle of rotation happened, and was it clockwise or anti-clockwise? Learners discuss and write their answer in their exercise books. Invite one pair from the middle ability group to share their reasoning. Confirm: Comparing A(1,1) to A'(−1,1), we see the rule (x, y) → (−y, x), which is 90° anti-clockwise. This task consolidates their ability to reverse-engineer the rotation angle from given points
Exercise
- 1Assessment Question — Rotation Drawing and Angle Determination. Write in learners' exercise books or on a worksheet: A rectangle has corners at P(2,1), Q(4,1), R(4,3), S(2,3). Draw this rectangle on a coordinate plane using a ruler and graph board. Now rotate it 180° clockwise about the origin and draw the image rectangle P'Q'R'S'. List the coordinates of P' and Q'. What angle would you rotate the original rectangle anti-clockwise to return it to its starting position? (Model answer hint: After 180° clockwise rotation, P'(−2,−1) and Q'(−4,−1). Rotating 180° anti-clockwise would return it to the original position, because 180° + 180° = 360°.) This exercise directly assesses the learner's ability to apply rotation rules in a coordinate plane and determine rotation angles, matching the Phase 1 objective
