I suggest introducing the topic from examples in life.

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.
