Year 1 Introduction to Subtraction Variety Pack | 2 Maths Units

Teach Year 1 subtraction within 20 through two complete units built for different teaching contexts. Both resources move from concrete and pictorial models towards equations and efficient mental strategies, while providing distinct lesson sequences, examples, games and assessment opportunities.

Introduction to Subtraction develops taking away and missing-part thinking with crossing-out models, part-part-whole diagrams, count-back practice, related fact families and school-fair word problems. Its Race Back to Zero game and Subtraction Story Match activity provide collaborative practice.

Introduction to Subtraction Updated expands the strategy work with number-line jumps, doubles and rainbow-to-ten facts. Caterpillar Count-Back cards, Rainbow Race, five further worksheet sets and two assessment tasks provide a fresh context for reteaching, maths rotations, intervention, consolidation or extra evidence.
