Shape patterns
图形规律
Description
Look for and use mathematical structure: apply properties of operations, place-value patterns, and relationships between shapes to solve problems efficiently
Mastery Evidence
- Use the commutative property deliberately (e.g. reorder 3 + 9 as 9 + 3 to count on from the larger number)
- Use place-value structure to add or subtract tens (e.g. 47 + 10 = 57 because only the tens digit changes)
- Recognise structural similarities between shapes (e.g. rectangles and squares both have 4 sides and 4 right angles)
Assessment Prompt
When your child notices a pattern in their maths work — like how multiplying by 10 always adds a zero — do they use that pattern to solve similar problems more quickly?
