Before measuring

Before measuring, we can estimate or guess the length of objects. We can use our hand span, footsteps, or known lengths to help estimate. Then we veri

We can change metres to centimetres

We can change metres to centimetres by multiplying by 100, and centimetres to metres by dividing by 100. For example: 2 m = 200 cm, and 150 cm = 1 m 5

Perimeter is the total distance around
