Instructional Ideas

• Give the absolute value inequality to pupils to solve prior to any instruction; challenge them to determine the solution without a formalized approach
• Encourage using a number line if a group has trouble starting

Classroom Considerations

• Requires a proficiency with solving linear equations and inequalities and a working definition of absolute value

Pros

• Highlights key misconceptions
• Includes a rubric to assess group discussion

Cons

• None
