Millimeters and Centimeters Year 3

Teach Year 3 students to measure length with care and explain their metric-unit choices. This complete unit develops understanding of standard units before focusing on millimetres, centimetres and metres. Students learn to choose an appropriate unit, connect 10 millimetres with 1 centimetre, convert whole-number lengths, read ruler intervals, align an object at zero, and subtract a non-zero start mark from an endpoint.

The package balances explicit instruction with partner games, guided practice, independent tasks, review and assessment. The editable presentation provides a clear learning sequence and worked examples. The editable quiz uses ten question-and-answer pairs, while the printable resource set supplies classroom display material, games, worksheets, answer support, a practical design task and a five-level rubric.
