Core Skills Analysis
Mathematics
Louie worked through a series of arithmetic problems that required him to apply the BIDMAS rules—Brackets, Indices, Division, Multiplication, Addition, and Subtraction. By simplifying each expression step‑by‑step, he practiced recognizing which operation comes first, correctly handling parentheses, and accurately performing calculations with exponents and mixed operations. This activity reinforced his ability to translate word problems into numerical expressions and to check his work for logical consistency. As a result, Louie demonstrated a stronger grasp of the order of operations, a core component of algebraic thinking at age 14.
Tips
Tips: Have Louie create his own set of real‑world word problems that require BIDMAS to solve, such as budgeting scenarios or recipe adjustments. Introduce a timed challenge where he must simplify increasingly complex expressions to build fluency under pressure. Pair the activity with a visual organizer that maps each step of the order of operations, encouraging him to annotate his reasoning. Finally, connect BIDMAS to algebra by rewriting the expressions using variables and exploring how the same rules apply.
