There are 20 cards in this activity that review solving equations (linear and quadratic), finding the distance and midpoint, evaluating a function, finding the slope of a line, and writing an equation given 2 points. You can use these as task cards or set them up in centers.
I use this activity on the first day of class. I give each student a card when they walk in the door along with an answer sheet. They first need to solve their own question and check the answer with me. Then have to go around the room and ask people for the other questions. They need to solve the question that the student has. Besides the work/answer on the sheet, they also have to write the other students name and ask them a question to get to know them. This is a great icebreaker activity and review at the same time.
