Many teachers have been frustrated by their attempts to teach students additions and subtraction of integers by using the number line. There have been many elaborate attempts to make the number line more accessable by having students actually stand on a number line and walk up and down while adding or subtracting integers, but it never seems to transfer to pencil and paper work. Well here is a method that works and works well for all students. It is fun, exciting and students love it. The idea is simple...if the signs are the same...it's a party, if the signs are different...it's a war. But what makes it effective are the leading questions that the teacher must ask in a snappy, fun, and exciting manner. Try it, you'll love Party and War. It works!
