Mathematics Measurement Conceptual 10–11 yrs

Measuring length (age 10+)

测量长度（10岁以上）

Description

Recognise volume as an attribute of solid figures; understand that a unit cube (side length 1 unit) has 'one cubic unit' of volume and can be used to measure volume; a solid packed with n unit cubes has volume n cubic units

Mastery Evidence

✓ Explain what 'volume' means for a 3D shape and how it differs from area
✓ Identify a unit cube and explain that it represents one cubic unit of volume
✓ Determine the volume of a small solid by counting the unit cubes that fill it

Assessment Prompt

If your child builds a solid shape using small cubes, can they count the cubes to find the volume — and explain what "one cubic centimetre" means in everyday terms?
