Year 3 Calculating Perimeter

A lesson designed to calculate the perimeter of simple 2D shapes. The lesson is based on finding the perimeter of rectangles and squares. There is an element of ruler skills for measuring sides of rectangles.

Finally, there is a ‘Chilli Challenge’ that can be supplemented with work that you feel suits the needs of your class based on AfL. I usually do fluency practice with children working towards the expected standard, varied fluency with children working at the expected standard and ensure my greater depth children are doing problem solving.
