Grade 1 addition worksheets
In first grade, children add single-digit numbers and practice the addition facts with numbers from 0 to 10. They solve addition problems with a missing number (missing addend), and use addition to solve simple subtraction problems. Children also learn some about 2-digit addition though that topic is continued in 2nd grade.
These worksheets are generated automatically each time you click on a link. You can print the worksheet directly from your browser window, but first check how it looks like in the "Print Preview".
If the worksheet does not fit the page in the Print Preview, adjust your margins, header, and footer in the Page Setup settings of the browser. Or, adjust the "scale" to 90% or less in the Print Preview. Some browsers may have "Print to fit" option, which will automatically scale the worksheet to be so small as to fit the printable area.
The problem sheets are randomly generated, so you will get a different one just by refreshing the page in your browser (press F5).
All worksheets come with an answer key.
