Perimeter war in Willow!

Today in maths, Willow were faced with a challenge set by the one and only Einstein. On a previous occasion, Einstein visited Broadford, with the intention of finding two dimensional shapes around the school with a specified perimeter. Although he was close to discovering the shapes, he was not close enough. Therefore, he challenged Willow to a 'perimeter war', asking them to explore the school and investigate perimeter. Many of the children were successful and managed to find 2D shapes, which were closer in perimeter to the ones Einstein found.
