Description
This Adding Tens and Ones Worksheet gives first graders focused practice combining a group of tens with a group of ones to build and add two-digit numbers. When children see that a number like 43 is simply 40 and 3 put together, place value stops feeling abstract and addition becomes something they can picture and explain. This adding tens and ones worksheet moves from base ten pictures to written problems, so students connect the blocks they count to the numbers they write.
Use this printable as morning work, a math-center task, homework, or a quick review before a place value quiz. Students begin with four base ten block problems, counting the tens rods and ones cubes to write each sum, then solve six column addition problems where they add ones to ones and tens to tens with no regrouping. A friendly apple-picking word problem finishes the page and shows how adding tens and ones works in a real situation. This tens and ones addition worksheet includes a full answer key, so it is easy to check work or let students self-check.
What’s Included
- 1 print-ready PDF worksheet
- Answer key
- 4 base ten block problems, 6 column addition problems, and 1 word problem
Practicing with this adding tens and ones worksheet helps children in three ways. First, the base ten blocks build a strong mental picture of place value, so students understand why the tens and the ones are added in their own places. Second, the no-regrouping problems let first graders gain speed and confidence before they move on to trickier addition with carrying. Third, the word problem asks students to apply the skill, which strengthens math reasoning and reading at the same time.
Teachers and parents can extend this skill in fun, hands-on ways. Build numbers together with real base ten blocks, craft sticks bundled into tens, or coins, and have your child say the tens and the ones out loud. Play a quick game where you call out a two-digit number and your child grabs that many tens and ones as fast as they can. You can also point out tens and ones in everyday life, such as counting a pile of stickers or grouping toys into tens, so children see that place value is everywhere.
