Multi-Step Problem Solving
多步骤解题
Description
Make sense of multi-step problems involving four operations, fractions, and area/volume by identifying sub-steps, choosing a strategy, and monitoring progress
Mastery Evidence
- 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
Assessment Prompt
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?
