What this sheet practices
Sets of 11–20 are where children stop counting in one smooth run and start losing their place. Grouping dots into tens and leftovers gives them a strategy beyond recounting.
Errors worth watching for
- Skipping a number in the teens (14 → 16).
- Losing track after 10 and starting over.
How to use it
- Set the difficulty. Easy narrows the range; challenge adds missing values or extra steps.
- Choose how many questions and how many fit on a page. Ten per page is the most readable default.
- Print, or save as PDF. Replace any single question with the circular arrow if it does not fit your group.

About this generator
Why do the dots look uneven?
Uneven sets force real counting. Neat rows can be answered by pattern-matching instead of counting.
How can I help at home?
Ask your child to circle ten dots first, then count what is left. That is the beginning of place value.
Can I print this worksheet on A4 paper?
Yes. Switch Paper to A4 in the settings panel. The layout recalculates the page height and keeps 0.5-inch margins, so nothing is cut off.
Is an answer key included?
The generator always produces an answer key and worked solutions. They are part of the pass; the student sheet can be previewed and printed for free.
