About this worksheet

This 2-digit + 1-digit addition (no regrouping) worksheet has 30 problems and fits on a single US Letter page. It is aligned to Common Core standard 1.NBT.C.4 and is typically used in 1st Grade, 2nd Grade. The problems are generated randomly each time you click New problems, so students can practice the same skill repeatedly without memorizing a fixed sheet.

Need something slightly different? Open Customize above to change the number of problems, the number ranges, or the layout. The link in your address bar updates as you go, so you can bookmark or share the exact worksheet you made.

Teaching tips for addition

  • Start with sums within 10 until they are automatic, then move to sums within 20. Fluency with these facts makes every later skill easier.
  • When introducing regrouping (carrying), let students use base-ten blocks or draw place-value charts for the first few problems.
  • Use the "No regrouping" sheets as a confidence builder before the "With regrouping" sheets on the same number size.
  • Short, daily practice (5–10 minutes) beats one long weekly session. Print a new sheet each day; problems are different every time.
