Solving Equations – Add It Up

I wanted a quick and fun way to assess students’ abilities to solve equations during the first week of school, so I made this “Solving Equations – Add It Up” powerpoint. Each group of four students will have one large whiteboard on their desks (purchased from Home Depot – panel board that is cut up). Each student will solve the problem in his/her quadrant, then the students will add all their solutions together to get one final number which they will write in the middle of the board. I will only look at that final number and tell a group whether they are right or wrong. If a group is wrong, they will have to look at each other’s work and figure out where the error has been made. During the activity I will walk around and monitor student’s progress, keeping notes on my clipboard for future reference.

If a group does not have 4 students, I will ask the student who finished his/her problem first, to also solve the 4th problem. If you do not have large whiteboards, you can still have students do this activity. Students can solve their problem on an individual mini white board or sheet of paper, and then combine their answers onto one sheet in the middle of the table.
