These lessons were written around Australian Curriculum strands and matched to Canadian grades by age (Kindergarten is the year before Grade 1). They are not mapped to any province's curriculum, and some use Australian examples, so check them against your province's learning outcomes and your own plans.

This topic is currently an outline — a full lesson with worked examples and practice questions is on our list. In the meantime you can build a lesson plan template for it, or find related worksheets.
