First, let children understand the different ways of addition and subtraction and have a basic concept of addition and subtraction.
For younger children, it may be too complicated for them to understand, so take the actual situation around them as an example to let them understand the meaning of increase or decrease. For example, a family is eating apples. If the father eats one and the mother eats two, then a * * * is eating several apples. For this situation related to the fruit eaten by family members in peacetime, children can better understand the quantity.
Second, you can also find out the actual teaching AIDS and let the children actually put them on the table.
Some people like to let children count their fingers when teaching them to do arithmetic. In fact, in addition to counting fingers, they can also take out some fun teaching AIDS in the back, so that children are more willing to do arithmetic through their interest in teaching AIDS, such as beautiful beads and a neat box of small sticks. These are all teaching AIDS to help children with basic arithmetic calculations. Let the children actually do an arithmetic problem on the teaching aid, and then count it. After several times of proficiency, they can count 1+2=3.
Third, mastering addition and subtraction within ten is the most basic foundation for children to do arithmetic in the future.
In fact, doing math is the same as learning Chinese. Chinese will help children master pinyin and simple Chinese characters, which will make future language and literature smoother. In learning mathematics, the teacher's internal addition and subtraction is the most basic foundation for children to do arithmetic in the future. If they are proficient in addition and subtraction within ten, they will do operations quickly and accurately in the future.
