Move it to prove it
Sometimes, all you need to do to prove a mathematical result is look at it in the right way. Explore these tasks to see how moving shapes can help you to prove results.
Visualising Triangular Numbers
You can visualise triangular numbers as a triangular array of little squares... Can you use the image to prove some triangle number relationships?
Dodecagon dissection
Grab a ruler, paper and scissors, construct a dodecagon, and cut it up. Can you reassemble it in a way to help you find its area?
Picture Story
It's said that every picture tells a story... Can you tell the story of our video about Cube Numbers?
