This activity is fun and gets your students up and moving and collaborating! Use this as a fun formative assessment to check your students' understanding of parallel and perpendicular equations in slope-intercept form. Print these slides 2 or 4 to a page and cut into cards. Randomly pass out 1 card to each student. (set has 24 cards) Then have students find the person who has their "parallel" equation or "perpendicular" equation. Set is purposely made to have pairs that fit either scenario. Comp
