Discuss how the children think they could solve this problem.
The Problem.
We want to make a school garden and grow vegetables. At night time the rabbits and deer will come and eat them. To stop them we need to put a fence around the area. However we can only afford to buy 26, one metre long panels.
Find the largest area we can fence off to make a rectangular vegetable patch?
- Remember it can only have a perimeter of 26 metres.
