Why Lesson Planet?
Yes, it does state that this is an English learners' worksheet, but the concepts addressed can be used in any math class that is learning how to add positive and negative integers. Four problems ask the learner to identify what sign is needed to make it correct. Three sentences follow that give the rules of adding integers, leaving out the words "positive" or "negative" to be filled in. You could work through this with your class as you are teaching the concepts and then have students keep it as a reference sheet.
