This file contains 6 pages. The first 2 are detailed lesson plans aligned to CCSS and Mathematical Practices and contain a warm up activity. Handout 1 is a introduction to the graph of the absolute value function using multiple representations. Handout 2 is a student practice with graphing transformations of the absolute value function. Handout 3 is designed to transition students into piecewise functions by having them write 2 linear functions and define the domain for each "half" of the absolute function. Page 6 is an exit ticket.
