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

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.

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.

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