Description
Write simple numerical expressions that record calculations with numbers, and interpret numerical expressions without evaluating them (e.g. recognise that 3 × (18932 + 921) is three times as large as 18932 + 921)
Mastery Evidence
- Write an expression for 'add 8 and 7, then multiply by 2' using parentheses
- Explain what 4 × (365 − 12) represents without computing it
- Compare two expressions and determine which is larger without evaluating
Assessment Prompt
Can your child look at '4 × (5 + 3)' and say 'that's 4 times the result of adding 5 and 3' — reading the expression as a description of a calculation, without having to work it out first?
