Multi-Step Problem Solving

Make sense of multi-step problems involving four operations, fractions, and area/volume by identifying sub-steps, choosing a strategy, and monitoring progress

How to tell they’ve got it

Tick these off as you see them — no test required.

Break a two-step word problem into parts and explain a plan before calculating
Choose between drawing a diagram or writing equations for a perimeter problem
Check a fraction-of-quantity answer by estimating: 3/5 of 20 must be more than half of 20

Try this together

When your child tackles a complex maths problem involving area, fractions, and multiple steps, do they plan their approach — estimating roughly what the answer should be before calculating, and then checking it makes sense at the end?
