  • 1Recall the correct sequence of operations in BODMAS and identify which operation to perform first in a given mathematical expression
  • 2Write on the board: 10 + 5 × 2. Ask learners: Which operation do we do first — add or multiply? Learners whisper their answer to their partner, then a volunteer shares aloud
  • UNDERSTANDING BODMAS IN PROGRAMME EXPRESSIONS
  • 1Open a text editor on the computer and display the line: result = 15 + 3 × 4 using the projector. Explain aloud that computers follow BODMAS just like we do on paper. Write the step-by-step solution on the board: Step 1 — Multiply 3 × 4 = 12. Step 2 — Add 15 + 12 = 27. Show learners that result now stores 27, not 72
  • 2Write three assignment statements on the board using Ghanaian context: score = 50 + 10 × 2 (Kwame's test score), price = 100 − 20 ÷ 4 (Ama's market purchase in GH₵), total = 6 × 5 + 8 (Yaw's harvest bundles). Ask learners to work in pairs and apply BODMAS to calculate the value stored in each variable. Circulate and check understanding
  • 3Struggling learners: provide them with a BODMAS chart showing Brackets, Orders, Division and Multiplication (left to right), Addition and Subtraction (left to right) and work through the first example together step by step.
  • 1Computer
  • 2Projector
  • 3Textbook
  • 4Board and marker
  • 1Ask a learner who finished the pair work early to come to the board and demonstrate the solution to score = 50 + 10 × 2, explaining each step using BODMAS aloud
  • 2Learners compare their answers with the person sitting next to them and thumbs up if both agree, or raise their hand if there is a difference to clarify together
Exercise
  • 1Write this assignment statement on the board: marks = 80 − 16 ÷ 2 + 5. Ask learners to calculate the value stored in the variable marks by applying BODMAS correctly and write their final answer in their exercise books with the working shown
