Lesson Details
Key learning points
- Scales are marked in different ways.
- Counting in 20s, 50s or 25s can help identify missing numbers.
- Knowing patterns can help you recognise whether numbers are multiples of 20, 25 or 50
Common misconception
Pupils may struggle to find missing numbers where they are given the start and end numbers only.
Draw attention to the patterns in the counts (e.g. 5 and 0 of counting in 5s and 50s) so that pupils recognise multiples of numbers.
