This activity contains 10 centers of 5 problems each. The problems review distribution and distribution plus simplification.
I group students in 3's or 4's. Each student is responsible for writing the problems and work. Once the group members agree on an answer, they write it out on the answer sheet provided. I typically have the student pass the papers from station to station, but a small well-behaved class would probably work well by movnig themselves around the room.
These stations typically take about 6-8 minutes to complete. I put a timer on the SmartBoard to keep time for the students as they work through each station.
I utilize this as a review activity prior to a quiz or test on introductory algebra material.
