Symmetry: gymnastics challenge
Two gymnastics-mad schoolchildren are taken to the Heathrow Gymnastics Club in Greater London. They meet Olympic gymnast Daniel Purvis, and are set a maths challenge related to gymnastics.
When doing gymnastics, it is very important for Daniel to make clean, symmetrical shapes with his body. The challenge is to take pictures of Daniel doing various moves and to mark on the photos the shapes and lines of symmetry.
Having completed the challenge, the two children are presented with medals by Daniel.
In pairs, the children could make as many different symmetrical shapes with their bodies as they can and keep a record. Bring the class back together and ask each pair to show their best shape. Photographs could be taken and annotated. Can pupils make pictures of any 2D shapes with more than one line of symmetry? What makes this difficult? Can they make pictures of any 2D shapes which have rotational symmetry? What might these look like?
