This simple but challenging trivia game has players guesstimate answers from topics ranging from how fast the earth spins at the equator, to how many television sets there were in the United States in 1951 to how many steps to the top of the Statue of Liberty. Each of the 200 cards has three questions on one side and the numerical answers on the other. The rules suggest that one player read one of the questions, the other players discuss and guess an answer, and the reader must say if the number is exactly right, over or under. However, it is easy to alter the game rules to let each person guess alone, play in teams against each other, or any other variation. This will help students learn how to think through the challenging questions and infer a logical answer based on what they know even if they are unfamiliar with the subject. The solutions are just the answers, so to ensure learning it will be important to include a way for players to discuss their thinking to understand how to approach the problem. Otherwise, students might make random guesses or tire of the game easily. Overall, Over/Under offers a great way to develop inferential thinking and problem solving skills provided students are actively analyzing each question and receiving appropriate support or encouragement throughout.
