(1) It is suitable for solving complex primary school application problems.

Teachers can consciously ask students to draw pictures to solve the related problems of "chickens and rabbits in the same cage", such as using ○ for the head and ∣ for the feet, and then draw the heads first according to the topic, draw the corresponding feet under each head, and then count them, and you may get the correct answer.

(B) applied to the teaching of basic mathematical concepts.

When teaching the concept of "cuboid volume", the letter A represents the length, B represents the width, H represents the height, and V represents the volume, which are presented in the form of pictures. Students only need to remember the formula V=abh.

Even if the formula is sometimes forgotten, as long as the figure is drawn, the basic properties of "cuboid volume" can be mastered naturally, and the formula will become more handy to use.

(c) Applied to mathematical understanding and problem solving.

In the process of teaching "score-score" knowledge, teachers can try their best to create a situation in which numbers and shapes are combined for students. Taking the classroom painting in the school summer vacation as an example, this paper puts forward the question-how many points can the decorators paint this wall 1/5 every hour, then 1/4 hours? Teachers should also carry out the ideological infiltration of the combination of numbers and shapes step by step.
