- 6. Playing and Learning Youoften see babies looking very intensely at something, or trying to put things into containers and taking them out again. As a child gets older the shape of the object becomes even more fascinating and often the child tries to put it into the right shaped container. Older children can begin to name more complicated shapes such as hexagons as well as being able to use shape and colour repetitively to create a pattern. The knowledge of how patterns work also allows them to predict what comes next. From the Science Museum, London, Patterns exhibition February 2013
