Draw a picture to illustrate the meaning of the following formula. 3x2 and 5x4；; 3×2 means there are three 2' s and 5×4 means there are five 4' s. The way to express its meaning through pictures is as follows: 1. Draw two objects and four objects on a plane. 2. Draw three and five groups of the above two groups of objects in the same way.

How to learn primary school mathematics well?

First, cultivate interest.

Interest is the best teacher, which I think everyone agrees. With the drive of interest, all the subsequent work will be much easier. In fact, mathematics itself is very interesting, at least when we first met it. It is not difficult for children to get in touch with mathematics, and it is not difficult to appreciate the fun of mathematics, but why do many students hate mathematics so much? I even shook my head when I saw the mathematical formula as an adult. I think this problem is largely caused by my parents.

Second, cultivate thinking.

Many parents told me that if children want to come to me to study mathematics and cultivate their mathematical thinking, they must pay attention to the cultivation of thinking in mathematics learning, but specifically, what is mathematical thinking? Or what is the main composition of mathematical thinking? My understanding of this is that mathematical thinking should include: classified thinking, abstract thinking and inductive thinking.
