Mathematics
Louie worked through a series of algebraic expressions using the BIDMAS rule, first identifying and solving any brackets before addressing indices. He then performed division and multiplication from left to right, followed by addition and subtraction, carefully recording each step. By checking his final answers against the original problems, Louie confirmed his understanding of the correct order of operations. This practice reinforced his ability to manipulate numbers accurately and boosted his confidence in solving more complex equations.
Tips
Tips: 1) Have Louie create his own set of mixed‑operation problems and exchange them with a peer for peer‑review, encouraging explanation of each step. 2) Introduce real‑world scenarios (e.g., budgeting or recipe scaling) where order of operations is essential, and ask Louie to model the situation mathematically. 3) Use an online interactive game that visualises each BIDMAS stage, allowing Louie to see immediate feedback. 4) Challenge Louie to convert word problems into algebraic expressions, applying BIDMAS to verify his solutions.
