✓ Select a ruler vs a metre stick based on the object being measured
✓ Decide when a number line is more useful than base-ten blocks for a given problem

Assessment Prompt

When your child faces a maths problem, do they think about which method suits it best — like doing easy ones in their head, using a written method for bigger calculations, or sketching a diagram for geometry?
