Why do this
problem?
This
problem will challenge children to find areas of
triangles on a square grid. They do not need to know a
'formula' as they could use the area of surrounding
rectangles to help.
Key questions
What is the area of the tent?
How could you find the area of this triangle?
How could you draw a rectangle around the triangle to help?
Possible extension
Some children might like to draw their own island on squared
paper and 'pitch' their own tents.
