Kindergarten Subtraction Lessons & Centres | Ontario 2026 Aligned

Are your Kindergarten students beginning to explore subtraction but needing concrete, hands-on experiences to truly understand how quantities change when objects are taken away?

This complete subtraction unit includes structured lessons and engaging centres designed to help students build strong subtraction strategies while developing deep number sense to 10.

Students explore subtraction using manipulatives, visual models, games, and problem-solving activities that support both conceptual understanding and mathematical communication.

This resource aligns with the Ontario 2026 Kindergarten Math Curriculum. The expectation remains the same — curriculum language has been updated for alignment.
