Instructional Ideas

  • Pick and choose videos that match your needs
Classroom Considerations

  • Concept video is a basic review of systems of equations; learners should have previously encountered systems of equations
  • Problem videos that cover solving systems by graphing use a TI graphing calculator
  • Problem 17 uses a system of equations with a quadratic equation and linear equation
Pros

  • Word problems leading to systems of equations use a variety of contexts
  • Well-paced and easily understood explanations
Cons

  • One of the videos (Problem 18) does not involve a system of equations
