Multi-Step Problem Solving

多步骤解题

Description

With teacher support, make sense of multi-step problems involving larger numbers or mixed operations by breaking them into parts, choosing strategies, and checking answers for reasonableness — children at this stage are developing the habit with guidance; independent strategy evaluation comes later

Mastery Evidence

✓ Break a two-step word problem within 1000 into sub-problems and solve each part
✓ Estimate an answer before calculating to set a reasonableness benchmark
✓ Check an answer using a different method or inverse operation and revise if needed

Assessment Prompt

If your child gets an answer that seems way too big or too small for a maths problem, do they notice and go back to check, even without you pointing it out?
