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
