Number and shape are two main parts in primary school mathematics teaching, and they are also the key and difficult points for students to learn. However, the effective combination of the two contents can simplify the learning process, combine the content of teaching materials with the actual teaching of teachers, and simplify complex problems.

First, the auxiliary shape of numbers-the relationship between numbers is clarified by the vividness and intuition of shapes. Such as "Fibonacci problem", which is often referred to as rabbit series.

Second, help the shape with numbers-refine the essence of things (graphics) with the help of the simplicity and generality of numbers. In teaching, image is put in an auxiliary position, and the characteristics of shape are described and explained through number, so that mathematics can achieve a deepening and rigorous effect.

For example, in the sixth grade teaching "Understanding of Cuboid", we can use the generality of "number" to understand the characteristics of cuboid, so that students can form the spatial concept of cuboid in their minds.

Combination of numbers and shapes:

The essence of the combination of numbers and shapes is to transform the quantitative relationship between mathematical knowledge and mathematical figures, so as to solve some heavy processes and contents in primary school mathematics learning.

For younger pupils, it is difficult for them to fully understand mathematics, so the combination of numbers and shapes can help pupils visualize mathematics knowledge in the process of learning mathematics and guide students to concretize abstract mathematics knowledge.

Cultivate students' thinking transformation ability, improve students' learning ability and deepen their understanding of mathematics knowledge. In the process of learning mathematical knowledge, the idea of combining numbers with shapes is also an important idea of basic mathematics.
