Identifying Tens and Ones Worksheet for Class 1
How many tens and ones are there in 35? This identifying tens and ones worksheet for Class 1 gives children practice reading a given number and writing how many tens and ones it contains. For example, 35 has 3 tens and 5 ones.
The activity helps children connect each digit with its position in a number. Use it for classroom practice, homework or revision after introducing place value with objects. The explanations and extra questions below support children as they learn to identify the tens and ones in single-digit and two-digit numbers.
How to Identify Tens and Ones in a Number
Start from the right. The rightmost digit of a whole number is in the ones place. In a two-digit number, the digit immediately to its left is in the tens place. Read the number first, then identify each position.
Example: 35
The digit 5 is in the ones place, so there are 5 ones.
The digit 3 is in the tens place, so there are 3 tens.
35 = 3 tens and 5 ones = 30 + 5
If the worksheet asks for ones first, write 5 ones and 3 tens. If it asks for tens first, write 3 tens and 5 ones. The order of the answer spaces changes, but the number remains thirty-five.
How Many Tens and Ones Are There in 9?
Nine is a single-digit number. It contains nine ones and no complete group of ten. When filling in a tens and ones chart, write 0 in the Tens column and 9 in the Ones column.
9 = 0 tens and 9 ones
6 = 0 tens and 6 ones
4 = 0 tens and 4 ones
To demonstrate this, give your child nine counters and ask whether they can make a complete group of ten. They cannot, so the collection has zero tens and nine ones. Write the numeral as 9; the zero is needed in the chart, not before the numeral.
Examples of Identifying Tens and Ones
Read each number aloud and check its digits. The chart below deliberately shows Ones before Tens, so children can practise following the column headings.
| Number | Ones | Tens |
|---|---|---|
| 9 | 9 | 0 |
| 17 | 7 | 1 |
| 35 | 5 | 3 |
| 40 | 0 | 4 |
In 40, the zero shows that there are no extra ones in its standard tens-and-ones representation. Four tens make forty.
Avoiding Common Tens and Ones Mistakes
Read the answer labels before writing. A child may understand 35 correctly but put 3 in the Ones space because they copy the digits from left to right. Ask them to point to the ones digit first and match it with the correct space.
Keep the number of tens separate from their value. In 35, there are 3 tens, and those tens have a value of 30. If the question asks “How many tens?”, the answer is 3. If it asks for the place value of 3, the answer is 30.
Compare 35 and 53 with objects when needed. Thirty-five has three tens and five ones; fifty-three has five tens and three ones. The digit positions explain why the numbers differ.
Extra Identifying Tens and Ones Practice with Answers
For each number, write the number of ones first and the number of tens second: “__ ones and __ tens.”

Answers, in ones-then-tens order:
1. 9 ones, 0 tens; 2. 5 ones, 0 tens; 3. 0 ones, 1 ten; 4. 4 ones, 1 ten; 5. 1 one, 2 tens; 6. 5 ones, 3 tens; 7. 0 ones, 4 tens; 8. 8 ones, 4 tens; 9. 3 ones, 5 tens; 10. 2 ones, 6 tens; 11. 0 ones, 7 tens; 12. 6 ones, 8 tens.
A Simple Read, Identify and Check Routine
Show your child one number at a time. Ask them to read it, identify the ones digit, identify the tens digit and fill in the labelled spaces. Begin with smaller numbers before adding a wider selection of two-digit numbers.
Check an answer by rebuilding the number. For 24, use two groups of ten and four loose counters. Ask your child to explain how the collection matches their answer. This checks understanding beyond simply copying digits.

Frequently Asked Questions
How many tens and ones are there in 35?
There are 3 tens and 5 ones. If the answer spaces ask for ones first, write 5 ones and 3 tens.
How many tens and ones are there in 9?
Nine has 0 tens and 9 ones because it does not contain a complete group of ten.
Which digit is in the ones place?
The rightmost digit of a whole number is in the ones place. In 47, the ones digit is 7.
Is the number of tens the same as their value?
No. In 35, there are 3 tens, and their value is 30. Read the question carefully to decide which answer is required.
How many ones are there in 40?
In its standard tens-and-ones representation, 40 has 4 tens and 0 ones. If all four tens are ungrouped, the same quantity can be represented by 40 individual ones.
How can I help a child who swaps the tens and ones answers?
Ask them to read each answer label before writing. Point to the rightmost digit for ones, then identify tens. Use objects to check the completed answer.
