1. Algebra Foundation: The algebra part of the seventh grade mainly involves the operation of integers, fractions and decimals. Students may need to adapt to new algebraic symbols and operation rules, such as solving linear equations, equations and inequalities.
2. Geometry: The geometry course in the seventh grade of junior high school began to involve more plane figures, such as polygons and circles. Students need to learn the basic concepts of calculating perimeter, area and volume, and master various geometric theorems and formulas.
3. Function and image: I began to learn the concept of function in the seventh grade of junior high school, including linear function and quadratic function. Students need to learn to draw function images and understand the properties of functions (such as monotonicity and parity). ), and solve the application of function in practical problems.
4. Data Representation and Analysis: The data representation and analysis course of Grade 7 involves the making of statistical charts (such as bar charts and line charts) and how to extract information from data. Students need to master basic data processing skills, such as average, median and mode.
5. Probability statistics: The course of probability statistics in grade seven of junior high school introduces the basic concepts and methods of probability, and how to collect, sort out and analyze data. Students need to learn to calculate the probability of events and use probability knowledge to solve practical problems.
In a word, the difficulties in the first volume of mathematics in grade seven mainly include algebraic basis, geometry, function and image, data representation and analysis, probability and statistics. In order to overcome these difficulties, students need to make efforts, do more exercises, and actively consult teachers when encountering problems.
