Practice that builds confidence
Understanding tens and ones
These Class 1 place value worksheets help children practise combining tens and ones to make two-digit numbers. Children learn that 3 tens and 4 ones make 34, and that the position of each digit shows its value.
The printable activities include number-building tasks, tens-and-ones representations, matching exercises, and write-the-number practice. They support children as they move from counting objects to understanding place value in written numbers.
Combining tens and ones is an important early place value skill. Children see that a ten is a group of 10 ones, and that a two-digit number is made from some tens and some extra ones. For example, 5 tens and 2 ones combine to make 52. This helps children read, write, and explain numbers instead of only memorising them.
How the practice progresses
The worksheets begin with clear tens and ones language, then move towards writing the complete number. Children may count tens first, count the ones next, and then combine them. They practise connecting representations such as bundles of sticks, base-ten blocks, tens frames, or place value charts with numerals like 27, 40, or 68. This supports both visual understanding and number writing.
A simple parent routine
At home, use straws, pencils, buttons, or rajma beans. Make small bundles of 10 and leave some single objects. Ask, “How many tens? How many ones? What number is this?” Then ask your child to write the number and say it aloud. Keep the routine practical: 2 tens and 6 ones, 4 tens and 0 ones, 7 tens and 3 ones. The zero-ones examples are especially useful because children often forget that 6 tens and 0 ones is 60, not 6.
Classroom uses for teachers
Teachers can use these pages during place value lessons, maths centres, morning practice, or small-group support. One page can be used for guided modelling, while another can be used for independent practice. The same worksheet can also become a quick oral activity: pupils explain their answers using the sentence, “There are __ tens and __ ones, so the number is __.”
Common errors to watch for
Some children reverse the digits and write 43 for 3 tens and 4 ones. Others count all the small pictures one by one instead of grouping tens first. A few may treat “tens” and “ones” as separate numbers and write 304 for 3 tens and 4 ones. Encourage them to point to the tens place and ones place, and to say the full number before writing it.

Helpful answers
Frequently asked questions
What does combining tens and ones mean in Class 1 maths?
It means using groups of ten and extra ones to make a two-digit number. For example, 4 tens and 5 ones combine to make 45.
Are these worksheets suitable before addition with two-digit numbers?
Yes. Children should understand how tens and ones form a number before they work deeply with two-digit addition and subtraction.
How can I explain 0 ones to my child?
Show only bundles of ten and no loose objects. For example, 6 bundles of ten and 0 single objects make 60. Say, “The zero shows there are no ones.”
What materials can I use with these worksheets at home?
You can use straws, ice-cream sticks, beads, buttons, pencils, or beans. Group ten together to show one ten, then keep loose items as ones.
Why does my child write the digits in the wrong order?
This usually happens when the child has not connected each digit to its place. Ask them to say “tens first, ones next” and use a place value chart before writing the number.
