The second part of 8 grade workbooks continue the march to higher level mathematics. In algebra, students encounter the basics of algebraic functions and their graphs, learn to solve systems of linear equations and inequalities, solidify their understanding of polynomial equations, and begin working with rational expressions.

**Overview**

The workbooks provide space for students to try the solved examples from the reading on their own, plus additional worksheets to further student understanding. In both books, the exercises contain problems that are extremely similar to the solved examples, as well as variations that require critical thinking skills to transform difficult problems into more manageable ones.

Their study of advanced geometry continues with a rigorous development of classic theorems on circles and their inscribed angles and polygons. In the final chapter, students get an introduction to combinatorics, a field often used to provide bridges between other branches of mathematics. Once again, the year’s curriculum ends with a summary of the ideas and techniques students have added to their personal mathematica toolboxes.

**The Workbook for 8th garde will strengthen the basic knowledge and skills needed to master the 8th grade mathematics material. **

To each topic in the 8B Textbook correspond problems in the 8B Workbook that every student should be able to solve. Some problems have a solution and some have the beginning of a solution. After working on such problems, students should be able to complete the remaining problems on their own.

**The 8B Worksheets highlight the basic knowledge in the 8B Textbook; have a teaching component;**

help students learn to organize and correctly write solutions to problems;

and save time for the teacher in searching for more problems.

**The 8 grade Math Worksheets can be used for independent work by the student;**

to assign homework;

to conduct tests;

and for practical work with applications.
