New thinking mathematics is a set of introductory teaching materials for children's mathematics based on the teaching principles of stimulating motivation, developing ability and learning methods. The content of the textbook consists of three parts: mathematical knowledge, intellectual problems and thinking stories. Each part embodies the three-factor teaching principle. Each part can not only become an independent knowledge structure and have independent teaching objectives, but also echo and complement each other, thus improving students' motivation, ability and methods. Each teaching unit consists of a mathematical knowledge point, a puzzle and a thinking story. This unique structure increases the interest and interactivity of learning and is more suitable for children's learning characteristics. It has a good effect on stimulating students' curiosity, activating thinking, improving learning interest and cultivating attention ability. This textbook breaks through the step-by-step and regular framework, and provides advanced knowledge, ability training and widely used methods. It is especially beneficial to students' follow-up study and provides students with development space beyond the normal level. Students who have been taught and trained by this textbook have the following remarkable characteristics: 1, flexible mind, great interest in learning and long concentration time; 2. Strong thinking ability and easy to accept new knowledge; 3. Broad knowledge and great potential for further study. These students show their advantages in regular schools. Early subtle systematic training shows their deep foundation and well-trained thinking ability in senior grades, especially in junior and senior high schools. Years of teaching have trained a large number of outstanding talents with full stamina, which has proved this point.
