First of all, we can make a budget with our children before going to the supermarket. First of all, we make a list of must-buy items, and roughly calculate the budget as 100 yuan. Make an agreement with the children. If the final price of the purchased items exceeds 100 yuan, then we will reduce several items from the list. If there is a balance of funds, then children can choose what they like to buy. If the remaining amount is not enough to buy things that children like, then you can save this change and wait until it is enough. This will not only allow children to have a certain plan for spending money, but also train children's ability to delay satisfaction.
Secondly, when visiting the supermarket, we should pay attention to guiding children to compare the price and type of every commodity they want to buy. Such as toothpaste, there must be many brands. Let's see which is the most expensive and which is the cheapest. Let the children add and subtract. If you do this often, your child's computing ability will also improve.
Thirdly, for younger babies, there are many shapes in the supermarket, and babies can come into contact with all kinds of shapes directly and in large quantities. Parents can guide the baby to know, for example, the bucket is cylindrical, the box is cuboid and so on. We can also teach the baby to count. For example, there are some bottles of detergent and some soaps on this shelf. Applying mathematics to life can better reflect its fun.
In short, the supermarket is also a paradise for learning mathematics. Parents can also simulate a supermarket scene at home, using paper instead of money to play the game of visiting the supermarket with their children. In this way, children can not only have a concept of money, but also learn simpler calculations in mathematics.
