Second, clarify the connotation of teaching materials and highlight the educational value. First of all, we should highlight the educational value of active substances. Teachers should be clear about what kind of materials can trigger what kind of activities and achieve what kind of goals. In other words, the transfer of activity materials should not be blind, but must be linked to specific goals and ensure the interaction between children and materials. Secondly, books and other materials should be placed next to the materials. Attaching images or words while providing materials helps children to establish the connection between objects and pictures, pictures and stories related to materials, thus providing children with diversified exploration and learning resources. For example, provide a simple operation chart in the area, or change the children's activity materials ... First, grasp the age characteristics and expand children's interests. In class regional activities, teachers should provide each child with colorful activity materials, so that children can decide what to play, who to play with, how to play with and what to play with, and actively interact with peers and materials according to their own interests, needs and wishes. Children's interest in participating in activities and the durability of activities are directly related to the delivery of regional activity materials. In order to make materials have educational value and effectively promote children's learning and development, teachers should provide materials that can fully attract and expand children's interests, so that materials can actively "talk" with children. This also requires teachers to grasp the age characteristics of children, take the stage training objectives of children in this class as the main basis, and consider the development needs and learning interests of each child. Only with richer materials and more diverse forms can children become active in the operation process. Second, clarify the connotation of teaching materials and highlight the educational value.

If a simple operation chart is provided in the area, or relevant pictures of children's activity materials are posted on the wall, the directionality and feasibility of children's exploration materials can be increased, so that it is easier to complete the operation activities. Third, you can use materials to emphasize a certain learning area. Effective material transfer can also be used as a tool to highlight a learning area. For example, provide interesting materials that can stimulate children's desire to explore in the science area, including interesting prisms, changeable colors, magnets, hourglasses, scales, wonderful turntables and so on. In the "living area", scissors, needle and thread and other living labor tools are added to let children learn basic practical skills such as threading and sewing.
