When using the sensorial equipment, the child learns basic concepts like size, colour and dimension.
Because the activities are both didactic and progressively more challenging, the child can learn at his own pace, moving forward only when he is ready. He is free to choose his activity and is thus able to move efficiently around the classroom.
The sensorial equipment builds a foundation for mathematics and language as it presents the various math concepts in concrete form. The child that has gained experience with the materials is also constantly interacting with the environment, and thus, communicating with the others around him and building up a vocabulary that will be vital for formal lessons later.
Sensory experience is important for the child to form his own understanding of the world.
Through the senses, the child is able to gain a firmer footing in reality and so begin to desire to know more about his world.
