Activity Overview
Students learn to locate the real number solution of a system of linear equations (two equations and two variables) with the help of tables and graphs. They also learn to graphically illustrate the types of solutions expected for a system of linear equations.
Before the Activity
Install Topics in Algebra 1 (Chapters 5) 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 5-1 to 5-7 from the attached PDF file for your class
During the Activity
Distribute the pages to the class.
Follow the Activity procedures:
Determine the number of solutions for a system of linear equations
In the activity System Match it!, use the knowledge of both functions and the graph and determine the correct answer
Gather information from a word problem and use induction to write a system of equations
Use the calculator to graph lines of a system of equations
Use the table to find the exact solution
After the Activity
Students will complete the Student Worksheet and analyze the results.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
