This review sheet is great to use as a pre-test or review sheet before a unit on money, adding to 100, and estimation. If you use it as a pre-test, you will get an idea on how much your students know, and how to differentiate for them. I used it as a review sheet that students could practice at home a couple of days before the test. I noticed that grades increased for the students who completed it, and practiced at home. You can even use it as a quiz, if you wish. Please remember to rate the product.
