Subtracting integers with both positive and negative numbers activity. In this packet you will get 32 subtracting integers questions and game rules. Students will race against other students or groups to try and get 10 of the same answers. Teachers, you will know that the magic answer in this packet is +12. Do not tell students .. Some secrets need to stay a secret! My 6th graders love this activity and work very hard to understand the rules (provided) usually they forget that they are even doing Math.
