In teaching activities, we often let children use pens, scissors and other items. There are also many hidden dangers. If teachers do not do a comprehensive safety work, it is inevitable that there will be safety accidents. In order to minimize the safety accidents in teaching, I think we should first educate children about safety and combine demonstration with explanation. For example, children should use pencils and scissors when writing, drawing and doing manual activities. Teachers should pay attention to intuition when demonstrating. If teaching children how to use scissors and pencils, teachers should first demonstrate, combine intuitive demonstration actions with language explanations, tell children how to use pencils and scissors correctly and remind them of the problems that should be paid attention to, and be careful not to cut their fingers or stab others, so that children can learn skills and know the knowledge of safe use. Secondly, we should actively guide them in life. Teach children to know and care for the five senses. Don't put foreign objects in your mouth, ears or nose. Teachers can tell children simply and clearly with pictures and mannequins that putting foreign objects in their mouths is unsanitary and dangerous. Putting a foreign body into the ear will cause the eardrum to rupture and cause deafness; Putting a foreign body into the nostril will block the trachea and cause danger. Another example is to educate children not to walk with strangers at will and not to eat food given by strangers. Children are usually trained to remember their home address, their kindergarten phone number and so on. When they get lost and can't find their parents or teachers, they will ask the police uncle for help. Children are curious, imitative and active, but their body movements are not coordinated, their self-protection ability is poor and they are prone to accidents. Therefore, it is very important to put children's safety in the first place and carry out safety education for children. Safety education for young children is not to instill profound truth in them, but to explain superficial safety knowledge in daily life, educate them to abide by daily life, let them know how to pay attention to safety and have a preliminary sense of self-protection.
