This was created for an 9th grade ESL class but can really be used for a typical 9th grade class as well. It is a PowerPoint Review game with 8 categories and 3 questions per category. The categories are: Propaganda, War Financing, Women, America Enters WWI, Causes of WWI, Weapons, Key Terms, and Surprise. I set the classroom into two teams and had them toss a bean bag through a board with several labeled holes. The labels were the aforementioned categories. Each team earned a point for a right answer. The other team could try for the point if the original team got the answer wrong. The students loved the review activity! You can modify this to use without the board by simply having the students pick the category they want. This also includes a detailed lesson plan with modification ideas.
