Calculating problems with positive and negative numbers always give my students trouble. Here is a worksheet for some extra practice. There are 24 problems - the first 12 are addition and subtraction, the second 12 are multiplication and division. I find that students can always benefit from extra practice on this skill. I have chosen the problems such that it would not be unreasonable to expect this to be done without a calculator, even for struggling students. The best part about this worksheet is that it is self-checking. When solved correctly the first column will spell DISCREPANTLY and the second column will spell VOLUNTARYISM. I find that using self-checking worksheets in my classroom makes it very easy to spot any mistakes quickly as I'm walking around the room or checking a paper. Please be sure to check out my other pre-algebra and algebra self-checking worksheets in my store as well! Enjoy!
