Instructional Ideas

  • Create a matching activity with values of x and equations with the goal to match the equations with the x-value that makes the equation true
Classroom Considerations

  • Scholars may want to solve the equations; remind them the lesson is about determining whether a particular value makes the equation true
  • Class members should be familiar with the distributive property and combining like terms
  • Part three in a 33-part series
Pros

  • Answer key provides the steps used to determine the solution
  • Scaffolding adds information for pupils that may struggle with algebraic notation
  • Complete with lesson plan, worksheets with addition exercises for classwork or homework, downloadable versions of both lesson and worksheets, and teach unit guide.
Cons

  • None
