What's in the Hand: Activity makes learning mode, median, mean, and range fun. You will need two packs of playing cards in order to use 10 different variations. I use giant clothes pins to hold a total of 9 cards for each station. Each student gets a worksheet and is assigned to a group of 4-5 students. Students will complete the first rotation by figuring the mean, median, mode, and range, and then rotate to each other station in about 5 min intervals. At the end they will answer the questions at the bottom of the page. I will include an answer key upon request with pre chosen card numbers.
