Struggling to incorporate reasoning and problem solving into your teaching of perimeter? We feel you! That's why we've created this Year 3 Calculate Perimeter Reasoning and Problem Solving resource, which focuses specifically on these skills. The questions are differentiated three ways, too, so there's something for everyone in your class.

Use as part of your lesson, as an intervention, or even send out as homework - the choice is yours. Make sure you check out our fluency resource and our modelling PowerPoint as they'll give your children an idea of what is to come in this resource.
