KS1 & KS2 maths curriculum

This unit develops understanding of place value by looking at 3-digit numbers. Pupils represent them in different ways and explore how counting patterns and mental calculation strategies familiar to them can be applied to larger numbers. They consider the composition and relative size of numbers, comparing, partitioning and positioning them on number lines. Pupils also develop counting patterns by counting on and back in multiples of 2, 20, 5, 50 and 25.

1. Represent a 3-digit number up to 1,000 in different ways
2. Count forwards and backwards within 3-digits
3. Position 3-digit numbers on number lines
4. Estimate the position of 3-digit numbers on unmarked number lines
5. Comparing and ordering numbers with 1, 2 and 3 digits
6. Ordering sets of 3-digit numbers
7. Use known facts to add and subtract multiples of 100 within 1000
8. Write a 3-digit multiple of 10 as a multiplication equation
9. Partition 3-digit numbers in different ways
10. Use known facts to solve problems involving partitioning numbers
11. Use known facts to add and subtract to and from multiples of 100
12. Add and subtract to and from a 3-digit number bridging 100
13. Solve problems by adding and subtracting to or from 3-digit numbers
14. Count forwards and backwards in multiples of 2, 20, 5, 50 and 25
15. Solve problems by counting forwards and backwards in multiples of 2, 20, 5, 50 and 25
