1, understand the concept of number. Parents should be more patient when teaching their children to count. Let the children read aloud and touch things with their hands. These things can be wooden beads, bowls, beans and so on. Because children can touch things with their hands, it can stimulate their interest in counting.

2. Learn the method of classification. Guide children to classify some things in daily life into one category, which can be classified according to different standards such as color, shape and use of objects. Parents should pay attention to guiding their children to find the standard of classification, that is, the similarities of things. This can also make children pay attention to the details of things and enhance their observation ability.

3. Understand the concept of order. Sequential practice is helpful to cultivate children's reading ability in the future, which is also an important way to train children's logical thinking. These orders can be from big to small, from hard to soft, from sweet to light, and vice versa. For example, mom and dad can bring several apples of different sizes, so that children can arrange them from big to small; Or bring things with different hardness for children to arrange according to hardness.

4. Know large groups and small groups. First of all, we should teach children the names of some related groups, such as furniture, sports, food and so on. Let children understand that each group has certain ingredients. At the same time, let children understand that large groups contain many small groups, and small groups are combined into large groups.

5. Establish a sense of time. Children's concept of time is very vague, so it is very necessary for children to master some words expressing time and understand their meanings. When children really understand the meaning of words such as "before", "immediately" or "immediately", they may be more disciplined.
