Looking for a purposeful way to help students understand the inverse relationship between addition and subtraction?
These inverse relationship task cards are designed to support students in recognising how addition and subtraction work together to solve problems with unknown values. Through carefully structured word problems, students learn to use known facts to find missing numbers, rather than relying on guess-and-check or rote procedures.

🌿 Explicitly teach and reinforce the inverse relationship between addition and subtraction
🌿 Support students to solve missing-number and unknown-start word problems
🌿 Small group or guided maths instruction
🌿 Whole-class maths rotations or stations
🌿 Independent practice for fast finishers or early finishers
🌿 Relief-teacher-friendly lessons with minimal preparation
