According to children's development needs, the curriculum design of early education for each age group is different. For example, children aged 7-30 months are the critical period of physical activity, so the main content of early education courses at this time is physical training; Sensory and math education is mainly aimed at children aged 28-40 months. At this time, the child's brain development is in a very active state, which is a good opportunity to know things and learn, and also a good opportunity to improve the child's intelligence. Art and music are mainly aimed at children over 16 months old, which is to cultivate children's interest. Not only that, but also consider the child's personality characteristics and so on.
