Check understanding
- Mentally compute 45 × 8 by partitioning into 40 × 8 + 5 × 8
- Use known facts to derive 6.5 × 4 mentally
- Solve a multi-operation mental calculation such as 250 × 3 + 500 and explain the strategy used
“Can your child work out a mixed calculation like '(200 × 6) + 350 − 75' entirely in their head — keeping track of each step without writing anything down?”
