Tens and Ones Build Worksheet

Two-digit numbers can trip kids up because the same digit can mean different things in different spots. This printable keeps the task small and clear by focusing on 11, 20, and 17. A first grader uses the learning models and writing fields to build each number as tens and ones, instead of guessing from the digits alone.

This page is a good fit when a child can count to 20 and is ready to slow down with place value. For 11, they connect 1 ten and 1 one. For 20, they see 2 tens and 0 ones. For 17, they work with 1 ten and 7 ones. That small set gives enough variety to notice the pattern without making the page feel crowded.

Sit nearby and ask simple questions as they work: “How many tens are there?” and “How many ones are left over?” If they swap the numbers, point back to the model and count it together. You can also cover one problem at a time with a blank sheet of paper, so the page feels more like a short conversation than a race to finish.

After this page, a helpful next step is to keep the numbers to 20 familiar in a different format. The Selected Numbers to Twenty Card Worksheet can give more practice recognizing numbers in that range. If your child needs a lighter warm-up with numeral matching, try the Numbers 5, 6, 7, 14, and 16 Matching Worksheet before returning to tens and ones.
