This game has improved my student's test scores by leaps and bounds. I couldn't imagine not allowing my students to play this game after I've seen the success that it's had. The midterm exam accounts for 25% of my student's grade. This game is an incredibly successful study tool.
Prior to a large test, give each student a study guide to fill out. After reviewing the study guide with students, have them create their own board game. The board game's theme must pertain to a topic that was covered in class. Next, the students must incorporate Q&A cards from the study guide and somehow utilize those question and answer cards into the games playability. Place the student desks into clusters of 2-3 and allow students to rotate around the room every 10-15 minutes to play the various board games that have been created. You may choose to give students a grade based on neatness, playability, theme, title, and the largest accounted grade should be for the question and answer cards. By the end of the class, the students will be more aware of some of the areas of study that they will need to focus on studying before taking the test. The best part of this project is that the students are having fun while studying.
