This challenge requires the use of a printer as the shapes need to be printed to the correct size.

If you are unable to print the worksheets out you are still able to take part in this challenge. Find some small objects around your home that you could use the draw around. Can you measure the perimeter of some of the shapes around your home?

Measure to the nearest CM and for an extra challenge you could try to measure to the nearest MM.

Can you create your own shapes and measure their perimeter? Perhaps you could order the shapes by the size of their perimeter?

Extra challenge: Measure in cm and mm so that you get decimal numbers. Can you add these together? Can you find two objects who's perimeter added together total between 1m and 1.5m?
