This is a great probability activity to use the day before a long break, such as Thanksgiving, or even in the afternoon of state testing days. The kids really enjoy playing BUNKO and their enthusiasm carries into the probability calculations. The best part is that you control the length of the actual BUNKO game... I've even let this activity carry over two days.
While the worksheet best matches the seventh grade Common Core, I've used it with sixth and eighth graders as well. I let the students work in groups of two or three to answer the questions, then we discuss as a group.
Even though we go over the rules of play together, I copy the last two pages back-to-back (then cut them in half) so the kids have a reference if needed.
