Perimeter

This is a lesson that I used to teach my year 6 class about finding the perimeter of a rectangle and of composite shapes. The lesson starts off with a starter on finding the factors of a number. It then offers opportunities to discuss the meaning of perimeter and to model the method. Next, there are slides with differentiated practice questions for the class to do on their whiteboards. The answers are on the next slides so that you can quickly check their work. On the penultimate slide there is the Learning Objective and a challenge to complete once they’ve finished their work. Worksheets are differentiated for LAs, MAs and HAs. I have included the answers for worksheets too to make teacher marking easier or for you to give to your class to mark their own work!
