From an early age children are developing a sense of order, and they actively seek to sort, arrange and classify.
The sensorial component to their development provides a key to the world; a means for growth in perception and understanding that forms the basis for abstraction of thought later on.
The sensorial materials initially give the child experiences in perceiving distinctions between similar and different things, e.g. hot/cold, smooth/rough, soft/hard. Precise language such as loud/soft, long/short, circle, square, cube etc is attached to these sensorial experiences to make the world even more meaningful to the child.
