Hi everyone, today we are going to learn perimeter in Year 3. So let’s get started.
What is perimeter
The perimeter is the distance around a 2D shape… You can imagine it as an ant crawling around the shape, so the area the ant will cover is the perimeter of that shape. The perimeter is normally measured in cm but can also be measured in mm and meters
Let’s calculate the perimeter of this shape. There are two ways to do it.
- Adding all the sides: 4+4+4+4=16
- Multiplying: instead of adding all the sides you can do it as 4×4=16 which is quite simple and quick.
3 steps to teach perimeter to kids
