Five addition worksheets in order, from sums within 10 for kindergarten to 3-digit numbers with carrying in second and third grade. Each one prints as it is, or you can change the numbers, the problem count and the layout first.

Ideas for using these sheets

  • Start one step below where a child is working: an easy first sheet builds the confidence for the next one.
  • Move up a skill at a time: facts within 10, facts within 20, then 2-digit numbers without regrouping and with it.
  • Pair each addition sheet with the matching subtraction sheet, so children see that 7 + 5 = 12 and 12 − 5 = 7 are the same fact.
  • Keep finished sheets in a folder and look back at the first one after a month.

Every setting can be changed above before you print, and “New problems” makes a fresh sheet as often as you like.
