Addition Worksheet Generator
Set one number range and a problem count, and every sheet comes out print-ready: US-letter formatted, aligned in the standard vertical (stacked) layout students meet on state tests, with generous workspace under each problem and a full answer key behind a toggle.
Teachers reach for this generator at three moments: warm-up drills at the start of math block (10–20 problems, one narrow range), differentiated homework (wider range, more problems, the link shared straight into your classroom app), and re-teaching a specific gap — because every sheet has a fixed, shareable URL, tomorrow's reteach group gets literally the same problems you previewed.

Ways teachers use this sheet
- Standard use: 20–30 problems, 3–4 minutes timed, score as a fraction at the top.
- Fact-fluency tracking: keep the same range and reseed the sheet daily; the layout stays identical so scores are comparable week to week.
- Intervention: halve the range and the count so success rates stay high while the strategy is being rebuilt.
FAQ
Is this addition worksheet generator really free?
Yes — no signup, no watermark, no download limit, no premium tier. Print as many sheets as your class needs.
Can I make the same worksheet twice?
Yes. Every sheet is pinned to the link in your address bar — the same link always produces the same problems, so you can save it, share it with families, or reprint it exactly as-is.
Does it include an answer key?
Every sheet has a matching answer key on the same page, folded away until you expand it. Print the page once with the key hidden for students and once expanded for yourself.
Which grades is this for?
Mostly grades K–3: single-digit facts (K–2), two-digit with regrouping (2–3) and three-digit addition (3). The range controls go higher if you need them.
