This file includes TWO mazes. The first one is for students to calculate the slope given two points. The second one is for students to find the slope given a graph.
I used both of these in the same class period to review before a quiz. However, these can be used separately to review each skill individually.
I printed them out on a smaller scale, and I instructed my students to glue them in their INBs. I do this with most of my activities and handouts to reduce loss of papers.
