## Linear Equations: Using Algebra

#### Activity Overview

Students learn to solve one-step and two-step linear equations. They understand algebraic concepts relating to linear equations such as isolating the variable, balancing equations, and checking solutions. Students also learn the properties of equality.

#### Before the Activity

Install Topics in Algebra 1 (Chapters 1-4) App on the calculator using one of these two methods:

• TI Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable
• TI-Navigator™  "send to class" feature
• See the attached PDF file for detailed instructions for this activity
• Print pages 2-10 to 2-15 from the attached PDF file for your class
• #### During the Activity

Distribute the pages to the class.

• Solve linear equations to find the values of x and list the steps used
• In the Solve It! activity identify steps to solve the given algebraic expression and find the solution
• For each equation, in the Beam Dale Up activity, select the right answer from the four choices given
• Read the equation as it moves down the calculator screen in the Free Fall activity and quickly solve for x
• Use the calculator to test the solution
