How to prove Pythagoras’ Theorem to Year 8? Paper and Starburst of course! The theorem states that in a right-angled triangle, the square of the hypotenuse (the longest side) is the sum of the square of the other two sides, but could the children be accurate enough to prove it works? First they had to construct a right-angled triangle and create squares of each side in different colours. Then they had to fill the largest square with the smaller two squares. This involved some very inventive cutting but they did a pretty good job at being accurate. Would this also work if the square was made from Starburst? Count the sweets in the picture to see.
