1 background of the problem Under the new curriculum reform, the purpose of mathematics education is to improve the students’ mathematical quality, thereby enhancing the ability of students to explore and expand the textbook is to achieve the curriculum objectives, the implementation of teaching an important resource. Textbook fully embodies the basic concepts of mathematics curriculum standards.Editors in the textbook “To students” proposed: This book in the content design on the design of some challenging content, including thinking, exploring, linking, and exercises in In order to stimulate students’ interest in exploring mathematics, many teachers in the actual teaching activities do not explain or direct the students to learn , While most students do not study,
