Last semester: (Generally speaking, this book is not difficult, mainly focusing on primary school content)

1, rational number

2. Addition and subtraction of algebraic expressions

3. One-dimensional linear equation

4. Preliminary understanding of graphics

Next semester: (This book is a transition to junior high school content, emphasizing problem-solving methods and skills, and it is also the learning foundation of the whole junior high school stage)

1, intersection line and parallel line

2. Plane rectangular coordinate system

Step 3: Triangle

4. Binary linear equation

5. Inequality and unequal groups

6, data collection, sorting and description

Three years of junior high school mathematics is still one per semester, one * * * six 29 chapters.

I hope I can help you!
