This is a game to review math addition and subtraction facts. The sample shows the starting slide and the question/answer for the grade 5 addition question. The full game has addition and subtraction questions for each level. Students select a category and click on it to get to the question. It can be answered by one student or you can have all students work the problem before clicking again to view the correct answer. Great class review game for TV/computer or SmartBoard. Works well as a two player game at a computer station also.
