There are a total of 12 problems on the first version, and 8 problems for the shorter version. You can choose which answer sheet to hand out: students can solve by graphing or solve by substitution. I personally use this for solving by graphing to review graphing linear equations. All systems have 1 equation in standard form (with integer x and y intercepts) and 1 equation in slope-intercept form and all answers are integers. If you have the students solve by substitution, there are a few problems that will require dealing with fractions. There are circuit worksheet versions of each scavenger hunt for students who are absent or cannot walk around the room.
For this activity, I cut up the half sheets and post them randomly around my room. The bottom of each half-sheet is a system, and the top of the half-sheet is the previous problem’s answer. I give students the answer doc and they can start at whatever half sheet they’re closest to. Once they write the answer down, they search for the answer on a different half sheet, write the name of the University, and complete the new problem.
