Add 3 numbers

This resource includes 5 focused worksheets designed to train children to add three numbers efficiently in two clear steps. Each page targets the core skills they actually need: spotting number bonds and using doubles to break calculations down quickly.

The worksheets follow a consistent structure so pupils know exactly what to do each time. They learn to identify the pair that makes a bond or double, complete that first step, then add the remaining number to reach the final total. No fluff, no distractions — just precision practice that builds confidence and speed.

Perfect for independent work, intervention sessions, or quick skills review. The tasks are simple to understand and effective for strengthening mental addition strategies.
