Stem-and-leaf plots, mean, median, mode, and range, fractions and decimals, its all here!! My students LOVED playing jeopardy. I would put them in teams or let them pick who was in their team. ALL students had to show work either on their desktops (with dry erase markers) or on the white boards they were using. Each student had a team job, and it was up to the team to work together and find a solution to each problem.
