1, knowledge structure: Unit 1-3 prepared in the first volume of Senior One mainly includes rational numbers, addition and subtraction of algebraic expressions, linear equations with one variable and other knowledge points. According to the logical relationship between these knowledge points, the knowledge structure can be sorted out and summarized to form a clear knowledge structure map.

Rational numbers can be divided into integers and fractions, then integers can be divided into positive integers, 0 and negative integers, and fractions can be divided into positive fractions and negative fractions; The addition and subtraction of algebraic expressions are divided into monomials and polynomials, and then monomials are divided into the product of numbers and letters, and polynomials are divided into the sum of monomials; One-dimensional linear equations are divided into equality and inequality, and then into one-dimensional linear equations and binary linear equations, and inequalities are divided into one-dimensional linear inequalities and binary linear inequalities.

2. Key points and difficulties: In Unit 1-3 of the first volume of Senior One, some knowledge points are difficult to understand and master. You can mark these knowledge points and analyze them as key points and difficulties.

In the operation of rational numbers, the addition, subtraction, multiplication and division of negative numbers are easy to make mistakes. These operating rules can be analyzed and illustrated in detail. In a linear equation with one variable, the steps of solving the equation are easily confused, so the steps of solving the equation can be decomposed and demonstrated.

3. Typical examples: There are many typical examples in Unit 1-3 of the first volume of Senior One, which can be collected and arranged to form an example library.

In the operation of rational numbers, examples of addition, subtraction, multiplication and division can be summarized; In algebraic addition and subtraction, we can summarize the examples of combining similar terms and solving linear equations of one variable. In the linear equation of one variable, examples of various application problems can be summarized. Through the analysis and practice of typical examples, we can deepen our understanding and mastery of knowledge points.

Making skills of mind map in senior one;

1. Use professional mindmanager: Using professional mindmanager can greatly improve the efficiency and quality of mind mapping. These softwares usually provide rich mind map templates and graphic elements, as well as powerful editing and typesetting functions, which can help users quickly create beautiful and clear mind maps.

2. Sort out the knowledge structure: Before making the mind map, sort out and summarize the knowledge structure of Unit 1-3 in the first volume of Senior One. According to the logical relationship between knowledge points, the knowledge structure can be decomposed and sorted out to form a clear knowledge structure diagram. This can help users better understand and master knowledge points, and also provide strong support for the production of mind maps.

3. Pay attention to beauty and clarity: the beauty and clarity of mind map is very important to improve learning effect and understanding ability. Therefore, when making mind maps, we should pay attention to the graphic layout, color and font design. Different colors and shapes can be used to distinguish different knowledge points and levels, and clear fonts and typesetting can be used to enhance readability.
