Italian educator Montessori believes that children learn by interacting with textbooks and learning toys. Children are not passive learners but active learners. They learn by engaging in various practical activities and practical operations on things, and promote the development of thinking and various abilities. The Guiding Outline of Kindergarten Education (Trial) points out that kindergarten education should respect the laws of children's physical and mental development and learning characteristics. In the course organization and implementation, kindergartens should provide rich operating materials for children and encourage them to actively discover, explore and learn.

However, there are some dangerous factors in handling materials. If the teaching AIDS are used, operated and managed improperly, it is likely to hurt children. In view of this, teachers must pay attention to the following points when using and managing teaching AIDS safely in kindergartens:

2. Positive guidance should be given to stimulate children's interest, encourage happy emotional experience, and avoid over-emphasizing the danger, which will lead children to be afraid to try or be too curious to cause accidents.

3. Tools and materials provided to children should meet the safety and hygiene standards, and certain safety measures should be taken, such as scissors with round heads, and small classes should not provide too small teaching AIDS.

4. Before playing with teaching AIDS, the teacher should count and check the number of teaching AIDS, so as to know fairly well. When you take back the teaching AIDS after class, you should count the number to avoid accidents.

5, in the process of use, encourage children to explore middle school, allow children to try their own unconventional usage, at the same time as a companion to participate in children's novel and exciting activities, always carefully observe, find problems, timely guidance, timely correction.

6. For tool materials that are easy to cause muscle fatigue, it is necessary to control the use time so as to avoid accidents caused by out-of-control muscles.

7. Carry out safety education for children in various forms, such as writing some children's songs to help children establish a sense of rules, cultivate good behavior habits and improve their self-protection ability.

In short, on the one hand, teachers should create practical opportunities for children, provide sufficient materials, encourage children to operate, try boldly and explore bravely to satisfy their curiosity, curiosity, fun and active nature; On the other hand, it is our duty to protect children, discover potential dangers in time, create a safe environment, improve children's awareness and ability of self-protection, prevent all kinds of accidents, and make children's physical and mental health develop harmoniously and comprehensively.
