Explain that students' games can be large, so the whole class can participate in them, or small, so a group of only 2-4 students can play at one time. Remind students that since they can't fit every fact into their games, they should prioritize and use the facts they think are most important. Give students adequate time to create their games. Set aside a day to play the games created by the students. Have students remain in their game-creating groups to play the games.
Groups can compete against one another during the large, whole-class games.
Let groups take turns playing the small games. Keep a chart of winners. Let students express constructive criticism for each group's game so that it can be improved. Ask students to comment on each of the following questions. Name them and tell why they were surprising.
