Tens and Ones Build Worksheet

1st Grade Math
English Counting & Number Sense Kindergarten Readiness 6 years old

Six-year-olds often understand counting before tens and ones feel natural. This printable gives them three friendly numbers, 17, 12, and 20, with clear models and writing fields so you can sit together and name how many tens and how many ones are in each number.

It works best when a child can count to 20 and is starting to notice that two-digit numbers have parts. If the place value words still feel new, point to the tens first and then the ones, saying, “17 is 1 ten and 7 ones.” Keep the pace slow and let the writing fields guide the answer.

As your child works, ask them to read each number, build or point to the tens and ones shown, and write the matching parts. The set includes 20, which is useful because it shows that a number can have 2 tens and 0 ones. That zero is often where kids pause, so talk it through instead of rushing past it.

After this page, a good next step is a little more practice with the same idea in a fresh layout. Try the Tens and Ones Number Cards Worksheet for more number card work, or use this related tens and ones number cards page to revisit place value another day without making the practice feel too long.

Frequently asked questions

What should my child know before starting?

They should be able to count to 20 and be ready to hear that a two-digit number can be split into tens and ones.

How do I explain the zero ones in 20?

Say that 20 has 2 full tens and no extra ones, then point to the zero in the ones place.

Should I correct mistakes right away?

It helps to pause and ask, “How many tens do you see?” before giving the answer, so your child can check the model again.

Can we do this page in more than one sitting?

Yes, you can finish one number, take a break, and come back to the next number when your child is ready.

How can I make the practice more hands-on?

Have your child point to the tens part and the ones part before writing, then say the full number sentence aloud.
