Lesson Activities by Day

Date	Phase 1: Starter (7 mins) Preparing the brain	Phase 2: Main (20 mins) New learning + assessment	Resources	Phase 3: Plenary (6 mins) Reflection + exercise
Tue 26 May 2026	1Recall the correct order of operations (BODMAS) when solving mathematical expressions 2Display the expression 2 + 3 × 4 on the projector and ask: 'What answer do you get?' Learners write their answer in exercise books, then compare with a partner	UNDERSTANDING BODMAS AND VARIABLE ASSIGNMENT IN PROGRAMMING 1Write on the board: Brackets, Orders, Division/Multiplication, Addition/Subtraction. Explain that computers follow this EXACT order. Use the textbook example on page 45 showing how a programme stores a number in a variable: score = 10 + 5 × 2. Work through it step by step: first 5 × 2 = 10, then 10 + 10 = 20. Show learners on the projector how the computer calculates this using an online Python compiler (or IDE on laptop) 2Ask learners to solve on their own: cost = 100 + 50 ÷ 2. Circulate and check their working. Call on a learner to explain their answer using BODMAS to the class. Use Computer/Laptop during the task 3Demonstrate on the computer/laptop: type into the programme: price = 8 × 3 + 4. Run the code and show that the result is 28, not 56, because multiplication happens before addition. Learners write the BODMAS rule in their exercise books	1Computer/Laptop 2Projector 3Textbook 4Online IDE or Python compiler 5Exercise books	1Show three expressions on the projector: (1) 6 + 2 × 3, (2) (6 + 2) × 3, (3) 12 ÷ 2 + 4. Learners solve all three in their books, then share answers in pairs 2Ask: 'Why did the answers change when we added brackets in expression 2?' Learners discuss, then one representative from a pair explains to the class that brackets change the order of operations Exercise 1Ama writes this code in her programme: total = 50 + 10 × 3 - 5. Using BODMAS, what value will be stored in the variable total? in their exercise books.
Thu 28 May 2026	1Identify and explain the correct order of operations (BODMAS) when evaluating mathematical expressions in a programme 2Write on board: 5 + 3 × 2. Ask learners to solve mentally and show fingers (1–10) with their answer—capture responses	APPLYING BODMAS IN PROGRAMME EXPRESSIONS 1Display on Projector: expression = (10 + 5) × 2 - 3 / 1. Write step-by-step solution on board: Brackets first (15), then Multiply (30), then Divide (3), then Subtract (27). Learners copy into exercise books and repeat the order chorally three times 2Open Textbook page showing variable assignment example: age = 15; cost = age × 50 + 100. Ask: Which operation happens first? Learners write answer in books; call on the group that finished first to present their working 3Using Laptop, display simple Python/pseudocode: total = 2 + 3 * 4. Ask learners to predict output (14), then show execution on screen. Highlight: multiplication before addition. Learners verify their written prediction matches	1Computer/Laptop 2Projector 3Textbook 4Exercise books 5Whiteboard and marker	1Learners compare their working from Phase 2 Section 1 with a partner; pairs identify one mistake (if any) and correct it together 2Select a learner who struggled with the starter to attempt this expression aloud: 20 / 4 + 3 × 2. Class nods or raises thumbs when they agree with each step Exercise 1Write: result = 6 + 2 × 3 - 1. Show your working step-by-step and state the final value of result following BODMAS order in their exercise books.
