First of all, you should spend more time with your children every day. What about the baby? That is to say to the children, let's play games.
The content of the game is "the mathematics content of preschool class", but it is not directly taught. Is to turn math content into games.
Like the count. Bring some toys and things that children like. Count how many there are.
If you have children, that counts. Addition and subtraction. We can bring little things that children like. Like building blocks. Take out some building blocks and ask the children, some building blocks. Take out a few more and let the children count how many are in a * * *. Take a few more back and calculate how many. You should also praise your children constantly. Make children happy and interested.
You can also play some games of pretending to buy things. One is a seller and the other is a buyer. It will also involve arithmetic and so on.
In short, children learn mathematics knowledge in unconscious play. And constantly praise the children. Let children enjoy playing such games with you very much.
This kind of game is not a day or two, we should stick to it every day. Therefore, parents should take some time to study while playing with their children.
