This center activity presents students with 16 equation cards and 16 answer cards. The task is to rewrite each equation in slope-intercept form (y = mx + b) and match the questions to their correct answers. A triangular prism with instructions and an answer key is included. Copy the question cards and answer cards on different colored paper. Students may work in pairs or individually to solve the problems. I use it at my Collaborative Practice table with students working in pairs.
