Teach adding and subtracting 1s with no exchange with our Year 2 Add and Subtract 1s Modelling PowerPoint. These slides cover a range of varied fluency and reasoning and problem-solving questions where children will add and subtract 1s without crossing 10. They will count on and back using number lines to support.

Use the answer slide following each question slide to model your working out. It is ideal to use as a scaffold for teaching how to add and subtract within 100!
