I used most of these cards at one time. It took my 12th graders close to 50 minutes to complete, so I went back and did them in groups of 5 for 6 matching games. You could do 10 pairs for 3 matching games. The cards are matched already. Each pair will have a card with black ink and one with red ink. That seemed to help the students. The vocabulary covers histograms, mean, median, samples, and types of samples, experiments and more. Feel free to make a copy and then use the template that is
