Introduction to Linear Combinations

How can you add equations and still end up with the same solution? Scholars first graph a system of equations to find the solution. They then perform operations on the equations and graph the resulting equation. They should see that the new equation passes through the original solution point, leading to linear combination as a solution method for systems.

Instructional Ideas

  • Have pupils develop their own systems to test out linear combinations
Classroom Considerations

  • Resource expects that learners already know how to solve systems by graphing
  • Instructors need to set up stations before the lesson
Pros

  • Provides a student resource sheet
  • Includes some notes and nuances for instructors to consider
Cons

  • Some parts of the resource do not load properly
