Exploratory play when a baby becomes aware of the world - sounds, sights, wanting to touch and taste.
Constructive play - to discover how things work, to take them apart, put them together again and learn about size, weight, colour, shape and materials and texture.
Energetic play; to practise new physical skills so that the growing child becomes better at running, climbing and other required activities.
Modelling - to learn from watching others and copying them.
Pretend play - playing in a world of fantasy and imagination usually without any interference from parents or other adults.
Social play - learning to play with others where those you play with are more important than the game itself.
