How it works

These 2 digit addition worksheets print with regrouping in every problem, in none, or mixed so pupils must look first. Other sheets add in a line, print carry boxes or squared paper, or set word problems.

Pick how much regrouping

The page opens on 2-digit plus 2-digit, with and without regrouping. For 2 digit addition without regrouping worksheets, choose Without regrouping: every column makes 9 or less under Sheet type. With regrouping: a ten to carry in every problem has one carry a problem. All three keep every sum below 100, so they serve as addition within 100 worksheets. Two more sheets carry into the hundreds.

Match the sheet to the mistake

An answer of 712 for 37 + 45 means 12 was written in the ones place: print A carry box over the tens, used or not. An answer of 72 means the carried ten was dropped: print Six to a page, with room to draw tens and ones, and have the ten drawn.

Questions and answers

What grade is 2 digit addition?

Grade 2 in both documents read for this page: Common Core 2.NBT.5 asks for fluency within 100, and Texas 2.4(B) has grade 2 add up to four two-digit numbers. So these double as 2nd grade addition worksheets.

What is 2 digit addition with regrouping?

A column makes 10 or more, so a ten is carried: in 37 + 45 = 82 the ones make 12, so write 2 and carry 1. For 2 digit addition with regrouping worksheets, choose With regrouping: a ten to carry in every problem.

Is double digit addition the same as 2 digit addition?

Yes. Double digit, two digit and 2-digit all mean numbers from 10 to 99. For double digit addition no regrouping worksheets, choose Without regrouping: every column makes 9 or less, or Without regrouping, written in a line.

How do I save a worksheet as a PDF?

Press Print, then choose Save as PDF in your browser's print window. That makes a 2-digit addition with regrouping worksheets pdf, or a PDF of any other sheet, with the answer key on its own page.

All 19 sheet types

With regrouping, without, or both 5

2-digit plus 2-digit, with and without regrouping The standard page: 12 problems in columns with every sum below 100. Some carry a ten, as in 46 + 38 = 84, and some do not, so pupils must look at the ones before they write. Common Core 2.NBT.5 asks grade 2 for fluency within 100.
Carry into the hundreds: the tens make 10 or more The ones behave and the tens do not. In 62 + 75 = 137 the ones make 7 and the tens make 13, which is 1 hundred and 3 tens. That 1 has no column waiting above it: it becomes a new hundreds digit.
Two carries: the ones and the tens both regroup Both columns make 10 or more. In 68 + 57 = 125 the ones make 15, so 1 ten is carried; the tens then make 12 with it, which is 1 hundred and 2 tens. The carried ten is the digit that gets left out.

With regrouping, without, or both, continued

With regrouping: a ten to carry in every problem The ones make 10 or more in every problem. In 37 + 45 = 82 they make 12: write 2, carry 1 ten, and the tens make 8 with it. Every sum stays below 100, so there is one carry to think about and no more.
Without regrouping: every column makes 9 or less No column adds to more than 9, as in 43 + 25 = 68: 3 ones and 5 ones make 8, and 4 tens and 2 tens make 6. The only work is keeping tens under tens and ones under ones, and starting on the right.

In a line, to add in your head 4

Near tens: add 19, 29, 39 or 49 by rounding The second number is 1 below a whole ten. For 26 + 39 = 65, add 40 and step back 1: 26 + 40 − 1 = 65. It is quicker than carrying, and it shows that the written method is not always the best tool.
Whole tens: 40 + 30 and the like Both numbers are whole tens, as in 40 + 30 = 70. It is the fact 4 + 3 = 7 counted in tens, and every answer ends in 0. A pupil who is slow here needs the single-digit facts, not more columns.
With regrouping, written in a line Printed in a line, and the ones always pass 10. For 48 + 36 = 84, add the tens first, 40 + 30 = 70, then the ones, 8 + 6 = 14, and last 70 + 14 = 84. No carried digit is written anywhere.
Without regrouping, written in a line Twenty problems printed in a line, such as 52 + 27 = 79, to add in your head: 5 tens and 2 tens make 7 tens, 2 ones and 7 ones make 9. With no ten to carry, the tens and the ones can be added in either order.

Headers, squares and carry boxes 4

A carry box over the tens, used or not A small empty box sits over the tens on every problem. In 57 + 26 = 83 it takes a 1, because the ones make 13; in 52 + 26 = 78 it stays empty. The box is printed either way, so it never tells which sums regroup.
H T O headers for sums past 100 The letters H, T and O stand over each problem, one digit to a square. In 86 + 47 = 133 the H column is empty in both numbers and still takes a 1 in the answer. The header shows where that 1 belongs.
Six to a page, with room to draw tens and ones Six problems to a page in place of twelve, such as 64 + 28 = 92. The space beside each one is for drawing 6 tens and 4 ones, then 2 tens and 8 ones, and ringing ten of the ones to trade for a ten.
Squared paper, tens under tens and ones under ones Each problem sits on squared paper, one digit to a square, with a spare row on top for the carried ten: 39 + 45 = 84. The squares keep tens under tens and ones under ones for a pupil whose columns drift.

Whole pages and mixed sizes 3

2-digit plus 1-digit in columns, ones under ones The 1-digit number is set under the ones, with nothing under the tens: 67 + 8 = 75. The ones make 15, so the tens digit changes from 6 to 7 though nothing was added to it directly. Common Core 1.NBT.4 names this size.
Thirty to a page, regrouping mixed Thirty problems on one page, such as 73 + 19 = 92, with regrouping as it falls and every sum below 100. There is less room to work, so keep it for pupils whose method is secure and who are building speed.
Within 100 warm-up, 1-digit and 2-digit numbers mixed Twelve problems in columns with sums to 100 and numbers of 1 or 2 digits mixed together, such as 58 + 7 = 65. It is the plain sheet: regrouping comes as it falls. Good for the first five minutes of a lesson.

Missing numbers, checks and word problems 3

Answer key with a subtraction check for every sum The sheet is plain sums with regrouping; the difference is on the key. Under 59 + 23 = 82 the key prints Check: 82 − 23 = 59, so a pupil marking their own work sees how taking one number away again tests a sum.
Missing addend: 32 + ___ = 44 One addend is a blank, and the pupil writes the number that makes the sentence true. For 32 and 44 it is 12, because 32 + 12 = 44. Counting up from 32 finds it, and so does 44 − 32 = 12.
Word problems with two 2-digit numbers Six short stories, each with two 2-digit numbers to put together, such as 32 pencils and 12 pencils: 32 + 12 = 44. The pupil picks out the numbers, adds and writes the answer on a line. Common Core 2.OA.1 asks grade 2 for word problems within 100.

How this list was compiled: Sheet types, wording and worked examples are own work. Every worked example, and every column total named in a description, was computed twice by script on 2026-09-30. Standard numbers and the wording taken from them were checked 2026-09-30 against the full text of the Common Core State Standards for Mathematics (California Department of Education copy, https://www.cde.ca.gov/be/st/ss/documents/ccssmathstandardaug2013.pdf): 1.NBT.4 (add within 100, including a two-digit number and a one-digit number, and a two-digit number and a multiple of 10; tens and tens, ones and ones, and sometimes it is necessary to compose a ten), 2.NBT.5 (fluently add and subtract within 100), 2.NBT.6 (add up to four two-digit numbers) and 2.OA.1 (addition and subtraction within 100 to solve one- and two-step word problems); and against the Texas Essential Knowledge and Skills for Mathematics, 19 TAC 111.4, adopted 2012 (https://tea.texas.gov/sites/default/files/ch111a.pdf): 2.4(B) (add up to four two-digit numbers and subtract two-digit numbers using mental strategies and algorithms) and 2.4(C) (solve one-step and multi-step word problems involving addition and subtraction within 1,000). Checked 2026-09-30 against Wikipedia: a carry as a digit moved to the next more significant column, https://en.wikipedia.org/wiki/Carry_(arithmetic) . The sheets follow no single curriculum, and naming a standard here does not mean a sheet is approved by anyone. Licence: own work
