Multiplicative Comparison

乘法比较

Description

Interpret a multiplication equation as a comparison (e.g. 35 = 5 × 7 means 35 is 5 times as many as 7); represent verbal statements of multiplicative comparisons as equations

Mastery Evidence

✓ Explain that '4 times as many' means multiply by 4
✓ Write an equation for: Sarah has 3 times as many stickers as Tom, who has 8 stickers
✓ Distinguish multiplicative comparison from additive comparison in word problems

Assessment Prompt

Can your child look at '35 = 5 × 7' and explain it as '35 is five times as many as 7' — understanding it as a comparison, not just a multiplication fact?
