This interactive whiteboard resource is inspired by one of the entries in the book: Professor Stewart’s Cabinet of Mathematical Curiosities
It focusses on repeating tiles where duplicates of a shape combine to form a larger version of the same shape. The picture above shows one such shape about to be completed. This can form part of a lesson on tessellation or investigating shape properties.
Each tile has 3 icons on it. One to drag it, one to rotate it, and one to flip it. The icons down the right hand side let you choose one of 7 different types of repeating tiles.
Also included is a collection of the shapes that can be downloaded, printed, and cut out so that the students can work individually on solving each shape. Some of the solutions require the shapes to be flipped so their reverse could be shaded by the students first.
