Learning journey
Your child is mastering more complex multiplication and division — working with larger numbers, understanding factors and multiples, solving multi-step problems, and beginning to use formal written methods.
Evidence of understanding
- Is 156 a multiple of 6? Explain how you know
- Find two square numbers that add to make 100
- Use factor pairs to simplify 24 × 25 as 6 × (4 × 25) = 6 × 100 = 600
