Since the implementation of the new curriculum, teachers have a further understanding of the development and utilization of teaching resources. "Mathematics Curriculum Standards" clearly points out that textbook writers, school administrators, teachers and related personnel should develop and utilize various resources consciously and purposefully according to local conditions. Therefore, we teachers are required to creatively use textbooks, actively develop and utilize all kinds of textbooks and teaching resources available for mathematics courses, and provide students with rich and colorful learning materials, so that our teaching content comes from textbooks and is higher than textbooks. Then, under the background of the new curriculum, how should teachers develop and utilize teaching resources? First, tap and flexibly use teaching materials to develop students' inherent potential. Textbooks are not the only curriculum resources, but they are still the main curriculum resources for teachers' teaching and the basis of teaching and learning. In order to improve the teaching quality, teachers must first understand and master the intention of writing new textbooks through research and analysis. Compared with the previous textbooks, great changes have taken place in the material selection and presentation form of the new textbooks. It not only considers the characteristics of mathematics itself, but also follows the law of students' learning mathematics. It emphasizes that starting from students' existing life experience and following students' psychological characteristics, students can experience the process of abstracting practical problems into mathematical models and explaining and applying them, so that students can gain an understanding of mathematical knowledge and make progress and development in many aspects such as thinking ability, emotional attitude and values.
