It can exercise children's small hand muscles, promote brain development, strengthen children's ability to recognize shapes and colors, cultivate children's good qualities and behavior habits of carefulness, concentration and patience, and cultivate children's imagination and creativity.

Child's ability training:

1. Learning ability. Children's learning ability is different from imitation ability. This learning ability refers to the ability of preschool children to master knowledge. To cultivate children's learning ability, we should start with cultivating interest. Let children learn on the basis of happiness, and let them learn independently and actively.

2. Creativity. Children's creativity and imagination complement each other, and improving children's imagination is the basis of building their creativity. Cultivating this ability can be exercised by visiting art exhibitions or museums. If families with conditions can let their children get in touch with painting art early, it is better to exercise this ability.

3. judgment. Only children who have their own choices and judgments can be more assertive. Such children are more likely to integrate into the society. To cultivate children's judgment, we should encourage children to express their ideas and guide them instead of violently interrupting some naive ideas.

4. self-control. Children's self-control is a kind of study of rules, so that they can understand that freedom has a scale and scope, and they can't act without fear.
