## Doubling Worksheets

Apart from learning how to multiply by two, doubling numbers is itself a useful skill that applies in many day-to-day activities. These addition worksheets focus on doubling of one and two digit numbers. This not only reinforces the essential addition facts, it helps in building the skills necessary to quickly solve multiple digit addition problems and regrouping mentally. Because the basic operations are a smaller subset of the math facts, it can encourage students to work on the steps for multiple digit addition.
