Tens and Ones Worksheet for Class 1
Help children understand two-digit numbers with this tens and ones worksheet for Class 1. Place value explains why a digit has a different value depending on its position. In 34, the digit 3 represents thirty and the digit 4 represents four.
This general Grade 1 maths resource supports practice with grouping, building numbers and identifying tens and ones. Use objects and drawings before moving to written answers. The original examples and questions with answers below provide additional activities alongside the worksheet available on this page.
One Ten Is a Group of Ten Ones
Place ten counters on a table and count them one by one. Put them together as one complete group. Explain that ten ones make one ten. The quantity stays the same when the counters are grouped.
Build twenty with two groups of ten, then add three loose counters to make twenty-three. Children can count ten, twenty, then twenty-one, twenty-two, twenty-three.
Use bundled sticks, base-ten blocks or drawn groups. Make sure every group contains exactly ten objects so the representation matches the number.
Read a Tens and Ones Place Value Chart
For a two-digit whole number, the left digit is in the tens place and the right digit is in the ones place. Read the positions and the complete number together.
| Number | Tens | Ones |
|---|---|---|
| 24 | 2 | 4 |
| 57 | 5 | 7 |
| 80 | 8 | 0 |
In 57, there are five tens and seven ones. Five tens have a value of fifty, so the number is fifty-seven.
Build Numbers and Write Expanded Form
Ask children to build four tens and six ones. Four tens make forty, and six more make forty-six. Write 46 = 40 + 6 to connect the grouped objects with expanded form.
Try the task in reverse. Show the numeral 32 and ask the child to make three groups of ten and two loose ones. Then write 32 = 30 + 2.
Keep the distinction clear: in 46, the tens digit is 4, but its place value is 40. The digit tells how many tens there are; the place value tells the amount those tens represent.
Understand Zero and Reversed Digits
In 70, there are seven tens and zero ones in its usual tens-and-ones representation. Build seven complete groups of ten with no loose counters. Zero shows that there are no extra ones.
Compare 26 and 62. Twenty-six has two tens and six ones; sixty-two has six tens and two ones. The digits are the same, but their positions change their values.
If a child reverses digits, rebuild both numbers with objects. Ask which collection matches the intended number instead of relying only on a handwriting correction.
A Hands-On Place Value Activity
Make two labelled spaces: Tens and Ones. Give the child a number card, such as 35. Place three bundles of ten in the Tens space and five loose counters in the Ones space.
Ask the child to read the number, explain the groups and write 35 = 30 + 5. Change the card and repeat with a manageable number.
For an extra challenge, add one counter to a collection with nine loose ones. Regroup the resulting ten ones as another ten. This shows why 29 becomes 30 when one is added.
