Unit 6 Review

To prepare for today’s review game, print multiple copies of the problem set. There should be enough copies for each group to have one set. Printing them on a different color for each group is helpful to keep from mixing them up. Cut up the problems and arrange them in your classroom somewhere for easy access. The students will be working through the questions one at a time. You'll also want to prepare your Post-Its with the point amounts on them and stick them to a poster or the whiteboard (see below for more details). Arrange students in groups of 3 or 4. Each group should come up with a team name and write it on the board.

Group members take turns coming up to the teacher to take ONE problem at a time. They work on this at their desks with their group members and bring it up to you to check. If it is incorrect, you will simply say “No” and send them back to try again. If the answer is correct, they take a new question to work on and head back to their group.

But now let's talk about the scoring. Every time a group gets a correct problem, they choose a Post-It note from the set you've put up (roughly 20-30 sticky notes) which have a number of points written on the back of them. But here's the catch, some of the Post-Its are Stinky Feet, meaning they have NEGATIVE points on them. So BEFORE the group sees the number of points they have to choose whether to keep the points or give them to another group. They randomly select a sticky note to determine how many points they earn for doing that problem. If they have chosen to give the points to another team, they can look at the value and THEN decide which team to assign it to. They should then adjust the scores on the board, and start working on the next problem.

The game ends when there are no more sticky notes left, or after an allotted time.

To make the sticky notes, write a point value on the back of 30 or so Post-It notes (we use pencil so they can’t see through it). Stick them to a poster or whiteboard. I write positive values between 0 and 10 on most of them but a few higher ones (15 and 20) and some negative ones, including one negative 20. I don't tell the students the distribution of positive and negative numbers.
