Solving Systems of Linear Equations with Linear Combinations (The Elimination Method)

Activity Overview

Students explore solving systems of linear equations with linear combinations (or the "elimination" method) from meaningful multi-representational approaches.

Before the Activity

Students should have familiarity solving linear equations for one variable and they should have a basic working knowledge of TI-Nspire CAS technology.

See the teacher notes document for complete instructions.

During the Activity

This activity is designed to be student-centered with the teacher acting as a facilitator while students work cooperatively. The student worksheet is intended to guide students through the main ideas of the activity and provide a place to record their observations and reflections.

After the Activity

Included in the activity is Problem 4—The Elimination Method that can be used as an assessment and evaluation of the students.
