Count 1 to 20 | Free Printable Worksheet
Worksheet preview — count groups of objects from 1 to 20, trace each numeral, and practice teen number recognition.
About This Worksheet
Counting to 20 is a kindergarten readiness benchmark, and this worksheet provides the structured practice children need to get there with confidence. The first ten rows review familiar territory, while rows 11 through 20 introduce the teen numbers — which are genuinely tricky because their names do not follow a predictable pattern (“eleven” and “twelve” give no hint that they mean “one-ten” and “two-ten”).
Each row pairs a numeral with a group of objects to count. For numbers 11 through 20, objects are arranged in two rows of five plus extras, helping children see that 13 is “a full ten plus three more.” This visual grouping strategy is directly aligned with the Montessori golden bead material, where children build numbers using concrete units and ten-bars.
This worksheet is ideal for children who have already mastered counting to 10 and are ready to push further. If your child is not yet comfortable with 1-10, start with our simpler counting worksheets and return to this one when they are ready. There is no rush — a solid foundation matters more than speed.

How to Use This Worksheet
- Review 1-10 first. Quickly count through the first ten rows to build momentum and confidence before entering new territory.
- Group the teens visually. When you reach 11, show your child how to see “ten and one more.” Cover the first ten objects with your hand and count what is left. This strategy helps children understand place value intuitively.
- Practice number writing. The teen numerals (especially 12, 13, and 15) are often reversed or confused. Let your child trace them slowly, saying the number as they write.
- Split into two sessions. Twenty rows is a lot for a 4-year-old. Do 1-10 in one session and 11-20 in another. Short, focused practice is always more effective than long, tiring sessions.
