The sensitive period of children under 4 years old mainly includes sequence, subconscious language, muscle development, walking, gross movements, independence, feeling and quantitative experience. In Montessori Studio, the development of these abilities mainly depends on the learning and operation of teaching AIDS in the field of life. I hope parents can find a match from the family life environment according to the supporting Montessori Family Education Law. On the one hand, daily life exercises train children to master various daily life skills, on the other hand, they cultivate children's self-confidence in living independently and gradually lay the foundation for their future family life and social life.

Children's sensory and quantitative experience is not abstract, and the sensory and mathematical teaching AIDS arranged in the teaching aid series are simple and classic. The sensitive period of children's reading and writing generally appears after the age of 4, so only "large and small English concave boards" are set up in language, and parents can help their children learn pronunciation and shape.

The child is about 3 or 4 years old, and the sensitive period changes rapidly. Sensory and mathematics are developing in the direction of abstraction and conceptualization, the sensitive period of reading and writing has appeared, and the demand for humanistic knowledge has increased. In view of this change, a large number of mathematics and sensory teaching AIDS have also been set up in household clothes, some of which belong to the extended scope. Social science has a corresponding map panel, and parents can make three-stage teaching cards according to Montessori family education law to help their children learn.
