I don't understand what the so-called primary school mathematics bulletin means. It is a publication for primary school students.

My suggestion is 1. Introduce the deeds of some mathematicians.

2. Consult relevant books, find some interesting math problems (addition, subtraction, multiplication and division in primary schools are understandable, but most of them are around the brain), and convey the view that mathematics comes from practice to students.

4. Introduce some interesting problem-solving methods.

3. Ask and answer questions about a flexible topic in life, and exercise students' ability.
