Writing Absolute Value Inequalities

Take one step at a time to assess the writing of absolute value inequalities. Presented with a verbal description of a one-step absolute value inequality, pupils write and solve the inequality. Learners develop a two-step absolute value inequality to represent a word problem dealing with a range of time.

Instructional Ideas
  • Review solving inequalities with a negative coefficient
  • Provide class members with an absolute value inequality and ask them to develop a word problem that would be represented by the inequality
Classroom Considerations
  • The class should be familiar with solving absolute value equations
Pros
  • Provides descriptions of common misconceptions
  • Is similar in construction to Writing Absolute Value Equations that allows the teacher to see if misunderstandings are the same for equations and inequalities
Cons
  • None
