WALT: measure perimeter

Today we will be learning how to measure and calculate the perimeter of simple shapes.


You will need a piece of paper, a pencil and a ruler for the session as there are some activities during the PowerPoint. If you don’t have a cm ruler there will be alternatives during the lesson. Please stay in the lobby whilst completing your work. You can get instant support as well as additional modelling after the input to ensure you’re completing the work accurately.


You have a selection of three challenges to choose from today. 

  1. No ruler – Purple Mash set. Questions about perimeter.
  2. Mild – Measure perimeter of 2d shapes.
  3. Spicy/hot – Measure, calculate and reasoning problems on perimeter.


I hope you enjoy the session today. Please upload your work to Purple Mash.
