Introduction
to Basic Algebra Tools
Pre-algebra – The 2nd grading period
The theme is solving one-step equations. Students will solve equations for the missing number. For example: x + 3 = 10. 7 + 3 = 10 so x must be 7.
Tip: The
difficulty in this chapter is solving these equations using positive and
negative numbers. For example: x – (-4)
= -23. This is the seventh graders first
exploration of abstract concepts in Algebra.
It is also the first chapter that is not a review of the sixth grade
work.
Students in chapter
3 will begin to learn all the rules for operations with integers. Here are some general lessons that can help
you learn more about this concept:

This is a continuation of Chapter 3. The main topic in this chapter is solving two-step equations. An example would be 2x + 3 = 11. The words two-step refers to the equation having 2 operations like add and multiply included in one mathematical statement. These equations take two steps to solve for the missing numbers.
Tip: Most students
will be able to transfer their skills from chapter 3 solving equations to this
unit. But again, the inclusion of
integers makes solving two-step equations challenging for seventh graders.
