I invented this class participation game to liven up reviews of science and social studies content. I have played it successfully with classes from fourth through high school levels. While playing the game the focus is on content, but a certain level of cooperation and stragegy is involved. It is a simple way to have students find the main ideas, key vocabulary, and assess their reading. I have also used it for shorter reading materials such as Weekly Reader. Stump the class can be played with an individual vs the class or in teams vs the class. The best part of the game is that you as a teacher are able to do an informal assessment of where the students are as far as knowledge and understanding of the content. I often use this as a pretest review and even have used the classes questions to generate the actual test questions. It is always ranked as one of my classes favorite activites of the school year. My name is Karen Isola Green, and I have taught for 35 years. I currently use this game as a substitute whenever I have a chance. It is a very adaptable game to all reading for information skills.
