Addition Within 100 Worksheets, No Regrouping

Two-digit addition practice where ones stay under ten, so students can focus on place-value alignment. Down at Pelican Pete's Harbor Depot, every cargo manifest keeps the ones under ten — containers hold ten, barrels hold one — so kids practice lining up tens and ones without a single spill.

Skill Focus

What this worksheet practices

No-regrouping addition is a useful first stop before exchange work. The numbers are still two-digit, so students must line up tens and ones, but the ones column never makes a new ten. That lets the page focus on place value rather than a second procedure at the same time.

For a second grader, the key habit is to read each problem by place: add the ones, add the tens, then check that the answer still makes sense. If a child says 45 + 32 is 77, ask where the 7 ones and 7 tens came from. That keeps the work mathematical instead of memorized.

This printable is intentionally calm and direct. It is not timed, and the answer key is separate so a parent or teacher can quickly check work without covering the student page. Move to the regrouping set once these are steady and mostly automatic.

FAQ

Addition within 100 questions

Should my child write these vertically?

Yes. Vertical work helps children see tens and ones clearly, even when regrouping is not needed.

Why avoid regrouping here?

It isolates place-value alignment before adding the extra exchange step.

What should we do after this page?

Use the addition-with-regrouping set when the no-regrouping answers are accurate and relaxed.
