Pupils should not hold the ruler to play with their classmates when using the ruler. Most of the rulers are made of plastic and are easy to break. The edges are also square corners. The children's skin is easy to scratch. Therefore, elementary school students must pay attention to safety when using the ruler, and the teacher at the school should also protect the child well so as not to harm the child. Pay attention to the following points when using the ruler;
1. Don't swing around in the air to avoid hitting other children.
2. Do not align your mouth and eyes to avoid being injured by other children, or stuffing your mouth to cause disease or injury.
3. Do not knock on tables, chairs and floors to avoid damaging the ruler.
There are many kinds of ruler materials used by students. Students often use plastic materials, which are convenient to use, but elementary students should pay attention when using the ruler, so as not to hurt the ruler.
