Collect the things related to mathematics in primary school students' life and dig out the details related to mathematics.

For example, students love spicy strips. You can turn multiplication into:

1 spicy strips 15cm, 10 How long are the spicy strips together?

What is the circumference of a square made of four spicy strips?

This is only a primary introduction concept, and it does not introduce attractive features into the core logic.

More examples need to be collected and excavated slowly in life.
