These are worksheets I use with my Pre-Algebra and Algebra classes to practice the rules of integers. They struggle a lot with keeping the rules separate, which is why I have them on different worksheets. Addition and Subtraction are on the first worksheet (see preview), Multiplication and Division on the second sheet, and finally a sheet with integer word problems using all 4 of the operations.
I do not allow my students to use calculators on these. With the exception of a few, most of the answers are whole numbers. And if they aren't whole numbers they are "nice" decimals that most students can do mentally.
