1. Cultivate children's observation ability: balls and boxes with drawers have different colors, sizes and shapes. By letting children observe, compare and classify these items, they can help children perceive more colorful things, enhance their interest in exploring things and improve their sensitivity to things.
2. Promote the development of children's sports: by taking out objects with different shapes and balls with different sizes and weights from the box, children can perceive the characteristics and shapes of objects through sports, and improve the ability to grasp objects and the flexibility of fingers.
