Choosing mathematical tools

选择数学工具

Description

Select and use appropriate tools and representations strategically: choose between mental, written, and diagrammatic methods; use calculators for checking; select fraction models suited to the task

Mastery Evidence

✓ Decide to use mental multiplication for 25×4 but a written method for 167×3
✓ Choose fraction strips rather than a number line to compare 3/8 and 1/4
✓ Use a ruler and squared paper to verify area by counting squares after calculating l×w

Assessment Prompt

When your child is working on maths, do they choose the right method — doing simple calculations in their head, using written working for complex ones, and sketching a diagram when a problem involves shapes or fractions?
