This word describes children’s experience when playing with materials that have different textures. Opportunity is provided to play with water, sand, mud, sawdust, gravel and relevant materials. In addition, children can here play with shapes that have a symbolic meaning, as in chess. The two sand pits facing each other emphasise the difference between the four corners of a square and the three corners of a triangle. These two forms were deliberately chosen to move away from the circular design of the building. Between the two sand pits is a low wall containing pipes of different shapes. The children can run the sand from one sand pit to the other through the pipes, while learning important concepts such as uphill and downhill. A chequered board, painted on the paving around the sand pits, provides for board games such as chequer-board, snakes and ladders and chess. The focus is Sensory development, exploration and discovery.
