1, the conventional mathematical problem-solving methods are fixed, and children can memorize the problem-solving methods through repeated exercises, so as to quickly find the correct problem-solving ideas when doing problems. Unconventional topics require children to have the ability to think independently and use mathematical methods flexibly. Such a topic is relatively new to children and requires high creativity and comprehensive application ability.

2. Conventional mathematical problems can be solved only by mastering some simple mathematical knowledge points, while unconventional problems often require children to master deeper mathematical knowledge and skills, such as mathematical reasoning and proof. This requires children to have higher energy and enthusiasm when learning mathematics in order to have better performance on unconventional problems.
