Perimeter Investigation

In this lesson, you will be carrying out a perimeter investigation. To calculate the perimeter of

a shape, you must ADD the length of each side. You can watch the video below to remind yourself how to find the perimeter of a shape.




First, calculate the perimeter of each of the enclosures. You will find that there may be more than one dinosaur that can be suitable for each enclosure. Make a note of all of the possibilities and make a final decision about which dinosaur should have which enclosure at the end. Remember to also watch Mr Pegram's teaching video to help you with the investigation.
