This book runs through the knowledge system of six core qualities, each with its own emphasis. For example, the two chapters of algebraic operation and geometric operation highlight the core literacy of mathematical operation. The six motifs in algebraic operations cover all operations from counting formulas to equations and inequalities. The four motifs in geometric operations cover all the operations of length, angle, perimeter and area.

In order to highlight the core literacy of intuitive imagination and logical reasoning, the third chapter "geometric drawing" is specially set up; The fourth to fifth chapters have 1 1 motifs, covering all the contents of graphics and geometry in junior and middle schools, and also focusing on the core literacy of logical reasoning and intuitive imagination.

Chapter six, seven and eight *** 15 motif covers all junior middle school functions and mathematical thinking methods, emphasizing the core literacy of mathematical abstraction and intuitive imagination; Chapter 9, two motifs in statistics and probability, highlights the core literacy of data analysis; Chapter 10, application problems, focuses on mathematical modeling, mathematical abstraction and mathematical application consciousness with the motif of 13.

Chapter 11 "Multiple Solutions to One Problem" covers the thinking method of classified discussion and combination of numbers and shapes in junior high school with four motifs, which highlights the comprehensive application of mathematical knowledge. In addition, each module has columns such as the source of the module, the original title of the module, knowledge orientation, literacy monitoring, thinking analysis and solving process. Each motif will be adapted in several directions, and the adapted test questions will have comments.

Reader feedback

Read the motif 60 times, look at a topic, close your eyes and think about it. I feel that Teacher Chen is right across from me. Tell me about the source and direction of this topic and why I chose this direction. It feels like holding hands and guiding one by one. That feeling is kind! Calm down, you can enter a book, a world, and do a lot of work on a topic.

Read the book carefully as soon as you get it. I was shocked by it just after reading a few pages. As the book says, "The more basic it is, the more important it is." For a simple example, through adaptation, different knowledge can be integrated and the core literacy of mathematics can be truly implemented in every math class. If every front-line teacher can do this, we can write a new chapter in mathematics education.
