In the Classroom

Pre-Experience (Things to Look Out For):

  • What does it mean to solve an equation?

  • What happens when you multiply both sides of an equation by a number?

  • Can you think of a time you used multiplication to manipulate an equation?

  • What would it look like to divide both sides of an equations by a number?

Post-Experience (Things to Think About):

  • In what ways are multiplication and division similar?

  • What strategy might you use to isolate x using multiplication and/or division?

  • What is an example of an equation that cannot be solved using addition/subtraction, but multiplication/division makes simple?

  • Can you imagine an equation that could not be solved?

  • What real-life scenarios might you model with an equation?

  • How might solving an equation be useful?
