Times tables (age 8+)

乘法口诀（8岁以上）

Description

Recognise and use repeated reasoning to generalise: extend patterns in times tables and equivalent fractions, derive unknown facts from known facts efficiently, describe general rules

Mastery Evidence

✓ Notice that all fractions equivalent to 1/2 have a numerator that is half the denominator
✓ Use the pattern 3×4=12, 3×40=120, 3×400=1200 and explain the generalisation
✓ Derive 8×7 from 8×5=40 plus 8×2=16 and describe the strategy as a general approach

Assessment Prompt

When your child notices a pattern — like that multiplying by 4 is the same as doubling twice — do they use that generalisation to solve similar problems more efficiently?
