Measurement for Kindergarten: Lessons, Centres & Activities (Length, Mass & Capacity)

Teach measurement in Kindergarten with simple, hands-on lessons and centres that help students explore length, mass, and capacity in a developmentally appropriate way.

This unit includes explicit lesson plans, math centres, and recording sheets designed to help students describe and compare objects while exploring measurement using concrete materials.

Activities are designed for whole group instruction, small groups, and math centres, making it easy to integrate measurement into your daily math block.

This resource aligns with the 2026 Ontario Kindergarten math curriculum expectations for Measurement (A10) and supports play-based, inquiry-based learning.

Curriculum Note:

The 2026 Ontario Kindergarten curriculum removed explicit mention of unit iteration. However, measuring with non-standard units remains developmentally appropriate for young learners and helps build important mathematical skills such as one-to-one correspondence and number sense.

Activities in this unit support students in describing and comparing measurements using concrete materials, which aligns with the current curriculum expectations
