Year 3 children are taught that addition and subtraction are inverse operations, and how that relationship can help answer different questions.

This Inverse Operations Varied Fluency worksheet gives children the chance to apply their understanding of how addition and subtraction are inverse to each other. They will complete partially-filled bar models, write fact families for part-whole models and find number sentences for real-life addition and subtraction contexts. Answers are also provided!

Other resources are available to consolidate learning further: a reasoning and problem solving worksheet, a discussion problem and a fluency matrix.
