Attention to the basic activity of mathematics experience is a major symbol of the modern evolution of mathematical education goals. The standard of compulsory education mathematics curriculum points out that teachers should play a leading role in handling the relationship between teaching and students’ autonomous learning, guiding students to explore independently, thinking independently, understanding and using mathematical ideas and methods to gain basic experience in mathematical activities, and at In mathematics activities, we constantly strengthen the training of mathematical thinking. Now the sixth edition of the Sujiao version of the book ”exercise of cuboids and cubes“ teaching activities as an example to illustrate. 【Math Activity】 Design a rectangular parallelepiped with six faces. ⑴ students according to the requirements of independent design. Teacher: Let’s do it together today. ”Little
