This product is designed to help your students practice adding and subtracting rational numbers (includes positives and negatives). Students will be given 20 expressions to add or subtract. There will be four problems per row. Three of the answers will be identical and one answer will be the ODD MAN OUT. If students do not get three matching answers per row, they will need to go back and redo their work. This is an easy to grade activity because students will need to shade in the Odd Man Out. This allows you to do a quick visual check to ensure that students are understanding the concept. This activity can be used as homework, guided practice, partner practice, centers, etc.
