Teachers, save “Perimeter” to assign it to your class.

Let’s learn all about perimeter! First, click on the and watch the video. Press On page one, carefully calculate the perimeter of each of the shapes, then use the button to type your answer inside the shape. Don’t forget to add ‘cm’ for centimetres or ‘m’ for metres too. If you’re feeling up for a challenge, head to page 2! There are three shapes here that you need to calculate the perimeter for, but not all of the information has been provided, so check carefully. Press when you’re done. Happy Seesawing!
