Adding Whole Tens And Ones Practice Activities
Printable Grade 1 place value worksheets for adding whole tens to one-digit numbers using tens-and-ones thinking.
Practice that builds confidence
Building tens-and-ones understanding
These Grade 1 place value worksheets help children add whole tens and ones, such as 30 + 4 or 6 + 50, by seeing numbers as tens and ones rather than as a string of digits.
The printable activities include clear equations, visual place value support, and mixed practice so students can connect base-ten ideas with mental addition.
Adding whole tens and ones is an early place value skill that prepares children for larger addition. Students learn that a number like 47 is made from 4 tens and 7 ones, and that 40 + 7 makes 47. The focus is not on carrying or regrouping; it is on combining a group of tens with single ones.
How the practice progresses
The worksheets move from direct combinations, such as 20 + 3, to equations where the parts may appear in either order, such as 8 + 60. Some problems may show the answer as a two-digit number, while others ask children to complete the missing total. This helps children understand that the value stays the same even when the order changes.
A simple parent routine
At home, start with a quick oral warm-up: say “5 tens and 2 ones” and have your child answer “52.” Then write three problems, mixing tens-first and ones-first examples. Ask your child to circle the tens, underline the ones, and say the full number aloud. Use dimes and pennies, craft sticks bundled in tens, or quick drawings of rods and dots if the written equation feels abstract.
Classroom uses for teachers
Teachers can use these pages during place value centers, small-group reteaching, morning work, or independent practice after a mini-lesson. They also work well as a quick check before moving into adding two-digit numbers without regrouping. Pair students and have one child read the equation while the other explains the tens and ones before writing the answer.
Common errors to watch for
Some first graders read 30 + 4 as 34 correctly but become confused by 4 + 30. Others may write 304 because they join the digits instead of combining values. If this happens, return to language: “30 means 3 tens, and 4 means 4 ones.” Encourage children to build or draw the number before writing it.

Helpful answers
Frequently asked questions
What does adding whole tens and ones mean in Grade 1?
It means combining a multiple of ten, such as 20 or 60, with ones, such as 3 or 8, to make a two-digit number like 23 or 68.
Should my child count on by ones for these problems?
Counting on can work, but the goal is place value thinking. Encourage your child to see 40 + 6 as 4 tens and 6 ones, which makes 46.
How can I help if my child writes 50 + 7 as 507?
Use objects or drawings to show that 50 is 5 tens, not the digits 5 and 0 to attach to 7. Have your child build 5 tens and 7 ones, then say and write 57.
Do these worksheets include regrouping?
No. This collection focuses on adding whole tens and ones without regrouping, so children can strengthen place value understanding first.
