Elsewhere on this site, I have some addition and subtraction worksheets for small numbers. This page provides an unlimited supply of long addition worksheets, that is, adding columns of multi-digit numbers. You can create as many worksheets as you like, choosing how many summands in each sum, and how many digits each one has. Once you've generated a worksheet, you can print it straight away if you like, or bookmark the link to the solutions. You'll even be given a permanent link to the additioon worksheet you'll have just generated - and it's safe to give this link to your students, since it's very hard to guess the solutions link from the worksheet link.
Since there are an unlimited number of worksheets available, you can always get fresh worksheets, and don't have to worry about whether students are copying answers from their seniors - or even their classmates, if you want to give a different worksheet to each student in your class!
If you aren't a teacher, if you're a student who wants some extra practice, or a parent looking for worksheets, you've found here more practice addition questions than you can use up in a lifetime, with the answers available for checking at the click of a mouse. Enjoy!
