Connecting Addition and Subtraction - Year 3

Build strong Year 3 understanding of the relationship between addition and subtraction. This classroom-ready unit teaches students to use inverse operations, identify wholes and parts, build fact families, solve unknowns in different equation positions and check solutions in the original equation.

The unit combines a 19-slide editable presentation with three practical activity families, eight sequenced worksheets, a 22-slide editable quiz and a Community Garden assessment. Students progress from recognising connected equations to selecting and justifying useful strategies for missing-number problems. Matching worksheet and assessment answers support efficient marking, while the landscape rubric describes performance from Beginning to Exceeding.
