Help Year 3 students become flexible and confident with subtraction. This complete mathematics unit explicitly teaches four useful approaches—split, jump, compensation and the written algorithm—then supports students to compare methods, choose an efficient strategy and explain their reasoning.

The sequence combines editable whole-class teaching slides with colour displays, a compact strategy toolkit, low-ink printable worksheets, a game-based activity, assessment and an editable quiz. Two- and three-digit examples build from place-value partitioning and open number-line jumps to friendly-number adjustments and regrouping in written calculations.

Learning focus

• Partition numbers by place value and recombine partial differences.
• Use efficient backward jumps on an open number line.
• Adjust to friendly numbers and compensate accurately.
• Align place-value columns and regroup when required.
• Select, apply and explain an efficient subtraction strategy.
• Check working and communicate mathematical reasoning.

Classroom use

Use the presentation and colour displays for explicit teaching and guided practice. Follow with the differentiated worksheets, strategy trail game and recording sheet. Finish the sequence with the mixed-strategy assessment, rubric and editable quiz. The unit is designed for approximately one school week and can be adjusted to class needs.
