Along with fractions, decimals are a basic part of mathematics and an essential skill for students. I have designed a one-page Acrobat (.pdf) page that helps to clarify the basic concepts of adding, subtracting, multiplying, and dividing decimals.
When learning the rules for decimals, it is important to have a teacher explain them step-by-step. This color print-out is designed to be a support while learning them for the first time, and then kept as a handy reference for practice or review. The left margin has room for punching three holes so it can go in a binder.
The design was kept as simple as possible; because it is an Acrobat file it will print clearly at high resolution. The whole point of it was to use COLOR, so please make color copies. No copyright.
