We thought you might like to know that the adding doubles worksheets were upgraded today. There used to be a limited choice of worksheets for using the adding doubles strategy. Now, you can find these worksheets in their own category on the Addition Page.

There are currently three ranges of numbers which we've called: small, medium, and large. The small worksheets basically cover the numbers from 0 to 9 although depending on the variation (e.g. Adding Doubles Plus 2), you might find numbers up to 11 on the page. The medium range includes numbers from 1 to 15 and may include numbers up to 17 on some of the variations. The large range includes numbers from 1 to 30 and may include numbers up to 32.
The nice thing about these worksheets is that we've controlled the repetition, so you will not see one question a number of times and another question not appear on the page. On the small range worksheets, each column of ten questions contains unique questions. On the medium range, each question appears twice, and on the large range, each question appears only once.
As with a number of math skills, we've chunked this skill into smaller bits for those who need it. The mixed variations worksheet, included in each range, allows students who understand the adding doubles strategy to apply it flexibly depending on how the two addends compare.
