Addition: 20 problems a sheet, 3 versions that do not repeat each other where the numbers allow.

How to use it

  1. Look at the sheet: it is a real, printable sheet. Switch between Sheet A, B and C, or press New numbers (N) for a fresh set.
  2. Change how many problems, how many versions, and whether the key prints. Settings stay in this browser; Share copies a link that rebuilds the same sheets.
  3. Press Print sheet A and key, or Print all. The answer key prints on its own page, so you can keep it back.

Ideas for class

  • Use base-ten blocks for the first three problems, so students see tens combine with tens and ones with ones.
  • Print the stacked layout. The line under the problem and the aligned digits are the whole point at this stage.
  • Follow it a few days later with the regrouping sheet, and ask students what is different about the problems.

Questions

How do I know no problem needs carrying?

Each problem is checked as it is made, and our tests check every sheet again by adding the digits column by column. If a sum in any column reaches ten, the problem is thrown away.

Can I include carrying later without a new sheet?

Yes. Open it in the maker and change Regrouping to Some with, some without. The same sheet then mixes both kinds, which makes a good review a week later.

Are the answer keys checked?

Each answer is worked out by the code that wrote the problem, and our tests recompute every answer a second way and compare. Please still look over the key before you grade a class set.

What this worksheet covers

Without regrouping, each column adds to nine or less: ones with ones, tens with tens, and the answer needs no carrying. Every problem here is built that way, so the sheet isolates the idea of place value in addition. Students are practicing the layout, the order, and the habit of lining up digits, with the carry left for the next sheet.

Who it is for

Second graders meet this under 2.NBT.B.5, which asks for fluent addition within 100 using strategies based on place value. It is the right sheet for the first days of the topic and a good diagnostic for older students who say they know it.

Adding two-digit numbers where no column carries · grade 2

A worked example

Add 43 and 25. Ones: 3 + 5 = 8. Tens: 4 + 2 = 6. The answer is 68. Ask students to say 40 + 20 and 3 + 5 aloud before they write it. Hearing it as tens and ones shows them why the columns line up.

Mistakes to watch for

  • Adding the tens first and then writing the answer backward, 86 for 68. Start at the ones, or say the answer aloud as tens then ones.
  • Misaligning the columns when copying a problem. Squared paper or a dark line down the middle helps.
