Here are two brilliant ways of using maths to create something awesome. Firstly, using fantubes, you can build a chair.
You would have to work out how many fantubes you need. Measure up a standard armchair and then divide the width and depth by the diameter of the fantube.
Or you could just count the number of fantubes in this picture. More info here. Then – this is the PR bit – invite the School Principal into Maths Class to sit on the chair. Will your principal have faith? Or chicken out?
Secondly you could make this folding cardboard chair.
