What are addition problems?

Addition problems are practice items where students find a sum, from single-digit facts in kindergarten to multi-digit addition with regrouping in 3rd and 4th grade. This generator writes a printable set at the grade and difficulty you choose, with an answer key. Each run writes new numbers, so two classes can get different pages.

What this practice builds

Addition runs through the Common Core from 1.NBT.C.4 (adding within 100 with models and strategies) to 4.NBT.B.4 (the standard algorithm for multi-digit numbers). Students who still count on their fingers for 56 + 27 slow down later on multi-digit multiplication, decimal addition, and combining like terms.

  • Sums within 10 for kindergarten and within 20 for 1st grade

  • Two-digit sums with and without regrouping for 2nd grade

  • Three-digit sums within 1,000 for 3rd grade

  • Multi-digit addition with the standard algorithm for 4th grade and intervention

What the output looks like

Ask for 20 problems within 100 and you get items such as 47 + 38 = ____, with a key listing 85. Items print on one line, so students who need columns copy them onto scratch paper. You can also ask for:

  • No regrouping, so sums stay clean (32 + 45 = 77)

  • Regrouping in every problem

  • Three addends

  • Missing-addend items (__ + 26 = 51)

  • Money amounts

How teachers use it

Use it for a weekly warm-up, nightly practice, or a sub-folder page. For a mixed page, ask for 'mixed addition and subtraction' or pair it with the subtraction problems generator.

How the math problem generator works

  1. 1

    Describe the set

    The topic and the format, such as two-step equations or fraction word problems about cooking.

  2. 2

    Set the details

    Grade, difficulty, and number of problems. It usually takes 10 to 20 seconds.

  3. 3

    Check and print

    Work a few problems yourself, then print the student copy and the answer key.

What teachers say

Teachers across subjects, from AP history to astrophysics, on grading with GradeWithAI.

“I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.”

“GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.”

Math problem generator FAQ

Questions about this tool? Email john@gradewithai.com.

Yes. Write 'no regrouping' in the description and the generator writes sums that need no carrying. That helps when you introduce two-digit addition and want students focused on place value first. Skim the page before printing.

Yes. The key prints on a separate page after the student problems. Turn the answer-key toggle off if you only want the student page.

Addition, subtraction, multiplication, division (including long division), fractions, decimals, ratios, percents, pre-algebra, Algebra 1 and 2, and geometry.

Yes. Ask for word problems in the description, and add a context such as sports, animals, or food if you like.

Pick the grade, which sets the kind of numbers and operations, then choose easy, medium, or hard.

No. It writes problems. To grade completed work, upload it to GradeWithAI, which reads handwritten math and gives partial credit under your rubric or answer key.
