Level Ups are a fun way for your students to practice or review defining functions and comparing functions. Aligned to the common core standards, this Level Ups activity includes 5 differentiated tasks that increase in rigor. The task cards begin with pre-requisite skills involving identifying the slope and y-intercept of linear functions in different representations, then "level up" all the way to creating and comparing functions that are both linear and non-linear.

Students start at level zero and work their way up to level 4, giving them accurate feedback on what they have mastered, and what they still need to work on. This lesson works as a great way to review what is and is not a function, or as preparation for an upcoming assessment.

This activity includes:

• Suggested activity instructions (based on how I run this in my classroom).
• Five levels with 6 - 11 questions each.
• Complete answer keys for each level.
