💡 How to Use This Worksheet

This worksheet is designed to be used as a follow-up activity after introducing the concept of subtracting within 20 to Year 1 students. It can be used in a small group setting, as an independent activity, or as a homework assignment. Before starting, ensure children have a good understanding of number bonds to 10 and can confidently count backwards. For children who are struggling, provide concrete resources such as counters, number lines, or ten frames to help them visualise the subtraction. Encourage them to draw pictures to represent the problem. For children who are confident, challenge them to create their own subtraction word problems or to explore related addition facts. Watch out for common mistakes such as subtracting the smaller number from the larger number regardless of the order in the question, or miscounting when using a number line. Extension activities could include using subtraction to solve simple money problems (e.g., 'I have 15p and I spend 6p, how much do I have left?').
