Giant POLYDRON is a superior play and construction tool that will lend itself to the task of making super construction sets and helping children understand spatial awareness from an early age, whilst having great fun. It encourages children to make and recognise 2 and 3 dimensional shapes and helps to develop an awareness of shape and texture. The set contains 20 giant PLOYDRON squares, 20 giant POLYDRON triangles, 6 coloured windows and 4 write/wipe-off panels. Each panel has a unique texture for easy identification. Incorporates braille on every piece to help children understand about alternative forms of communication. Add the panels to make dice, to draw letters, numbers or pictures. The panels simply clip into Giant POLYDRON or XL POLYDRON and are durable and safe to use either indoors or outdoors. Add the windows to allow children to see the world from a different perspective. They can also experiment by blending the windows to create new coloursGreat for early mathsEncourages spatial awarenessSupports creative thinkingContains: 20 giant Polydron squares, 20 giant Polydron triangles, 6 coloured windows and 4 write/wipe-off panels.Age Suitability: 2 Years +
