A comprehensive approach to teaching beginning algebra.
Students investigate the symbols and rules of algebra and how they are used to represent relationships. They learn how to solve linear equations, progress to graphing linear functions and systems, and study linear inequalities and absolute values. Lessons and activities include:

The Language of Algebra
• Variables, expressions, and equations
• Linear equations in one variable

Linear Functions and Equations
• The rectangular coordinate plane
• Introduction to functions

Systems of Linear Equations
• Graphing solutions of linear systems
• Algebraic solutions of linear systems

Linear Inequalities
• Inequalities in one variable
• Inequalities in two variables
