From birth to 6 years of age, the child is absorbing everything directly from the surrounding environment, much like a sponge absorbs liquid. It is during this phase that many language and motor skills are acquired and the child reaches a point in which repetition and manipulation of materials in the environment are critical to the development of concentration, coordination, independence, and a sense of order. The child learns skills for everyday living, sorting, grading, classifying—all of which lead to the development of writing, reading, and a mathematical mind.
