Tens and Ones Build Worksheet

Teen numbers can trip kids up, especially when 14, 17, and 19 all sound alike at first. This one-page kindergarten math worksheet keeps the job small: look at each number, build it as 1 ten and some ones, then use the writing fields to show the tens and ones.

This page is a good fit when a child can count small groups and is starting to see that a teen number is more than “a 1 and another digit.” If counting still feels shaky, warm up with the circle counting and drawing worksheet first, because it gives extra practice counting visible groups before moving into place value.

As you work together, point to the whole number first, then say it slowly: “Nineteen is one ten and nine ones.” Have your child count the ones out loud, trace or write the numbers in the fields, and say the matching tens-and-ones sentence. The same pattern repeats for 19, 17, and 14, so the practice feels familiar without turning into a long drill.

If your child guesses, pause and cover the written answer for a moment. Ask, “How many tens? How many ones?” and let them count again. For a next step, try the next number to ten worksheet to practice number order, which supports the counting language children use when they build teen numbers.
