Instructional Ideas

• Incorporate with other videos from this series to teach each method of solving linear systems
• Ask your classes to compare and contrast the three methods of solving systems

Classroom Considerations

• Meant as a review of the three methods of solving systems: substitution, elimination, and graphing

• This video is hosted on YouTube

Pros

• Uses the same system throughout to illustrate the similarities and differences in the methods
• Leaves all three methods on the same screen to allow for comparisons during the entire lesson

Cons

• None
