Show your class members that if they can graph a linear function, they can graph an absolute value function. Groups create an absolute value graph using a table, then entertain the idea of an absolute value function defined as two pieces of linear functions. The resource also includes the greatest inter function.

Instructional Ideas

• Use board work after each example to check for understanding; assign practice problems at the end
• Emphasize the meaning of the open and closed circles of the piecewise graph

Classroom Considerations

• If piecewise functions is a new concept for students, it may be necessary to extend to multiple days to ensure time for understanding
• The 16th installment of a 26-part series

Pros

• Allows groups to make their own discoveries of the absolute value function
• All handouts, keys, and a detailed teacher guide are included
• Introduction and exit ticket are provided

Cons

• May advance too quickly for Algebra I students
