A series of 10 handouts with a review of addition, subtraction, multiplication, division, place value, and rounding. Answer sheets are included with each handout. My intention of using these packs would be for busy work or for students to challenge themselves after completing the tasks at hand for the day. I would use these as incentives - if they completed a page, I'd give a sticker that they could collect for potential rewards. These also work as good reviews of particular concepts :)
