Tamar Class Explore Diagonals in Regular Polygons 13 Nov 2014

In our maths lessons this week we have been exploring the properties of 2d shapes. We have learned a lot about the diagonals of shapes and are now able to recognise a quadrilateral from its diagonals, using vocabulary such as intersect and bisect.
Today we explored the diagonals of regular polygons and used sharp pencils and rulers to draw them. They make beautiful patterns called ‘mystic roses’. We wanted to find out how many diagonals each polygon had, so we had to work systematically and take notes of what we discovered. There IS a pattern in the numbers, and as I write this post there is a buzz of excitement as children begin to uncover it.
