1. First of all, it should be closely combined with education and teaching activities. This kind of competition is not a simple manual competition. The purpose of the competition should be to promote teaching. Therefore, it is suggested that teachers attach an activity plan while making teaching AIDS, and explain the significance and application ideas of playing teaching AIDS.

2. Secondly, it should be acceptable and liked by children. The ultimate goal of making teaching AIDS is to promote children's learning, so what is the significance of making teaching that children don't like and can't play? Therefore, I suggest that in addition to the evaluation of children, children should also choose their favorite teaching AIDS.

3. Durability. Playing teaching AIDS is to stand up to children's play and fiddling. How can you play with teaching AIDS such as tofu?

4. Environmental protection. The materials used in kindergarten to make teaching AIDS should come from the children's real life and should be recycled. On the one hand, children can do it themselves when they go home, and environmental protection is also considered.
