Practice that builds confidence
Building a base-ten picture
These Grade 1 place value worksheets focus on the key idea that two-digit numbers are made from tens and ones. Children practise seeing 34 as 3 tens and 4 ones, not just as digits side by side.
The printable activities include base-ten blocks, tens frames, bundles, place value charts, matching tasks, number writing, and simple composing and decomposing questions. They are designed for steady practice within the Math > Grade 1 > Place Value > Tens Ones skill.
Tens and ones work helps first graders connect counting to place value. A full group of ten becomes one ten, while the extra counters are ones. Worksheets may show rods and cubes, bundles of sticks, filled ten frames, or a tens-and-ones chart so children can move between a picture, the words, and the number.
From counting to composing numbers
Practice usually begins with identifying how many tens and ones are shown. It then moves to writing the number, drawing a model for a number, and completing statements such as 4 tens and 2 ones = 42. Children also learn that 20 has 2 tens and 0 ones, which is often harder than numbers with visible leftover ones.
A simple parent routine
At home, start with real objects such as straws, craft sticks, or small blocks. Ask your child to make groups of ten, tie or stack each group, and count the leftovers. Then match the model to a worksheet question. Say the number both ways: 56 is fifty-six, and it is 5 tens and 6 ones. End by asking your child to draw the tens as long bars and the ones as small dots.
Classroom uses for teachers
Teachers can use these printables for place value centers, small-group reteaching, morning work, or quick checks after a hands-on base-ten lesson. The mix of visual models and written responses helps reveal whether a student understands the value of each digit or is only counting individual pictures.
Common errors to watch for
Some children reverse the digits, writing 24 for 4 tens and 2 ones. Others count every cube one by one even when rods are shown, or forget that zero ones still needs a 0 in the ones place. A child-friendly strategy is: Count the tens first, whisper ten, twenty, thirty, then count the ones and write tens digit, ones digit.

Helpful answers
Frequently asked questions
What does tens and ones mean in Grade 1 math?
It means understanding that a two-digit number is made from groups of ten and single leftover ones. For example, 37 has 3 tens and 7 ones.
How can I help my child if they mix up the tens and ones digits?
Use a place value chart with two columns. Have your child place or draw the tens first, then the ones, and write the digits directly under the matching columns.
Are these worksheets only for children who already know base-ten blocks?
No. The worksheets support children as they learn the connection between pictures, grouped objects, and written numbers. Hands-on blocks or bundles can be used alongside the pages.
Why is 40 written as 4 tens and 0 ones?
Because 40 has four complete groups of ten and no extra single ones. The zero holds the ones place so the 4 keeps its value as tens.
How should teachers use these tens and ones worksheets in class?
They work well after a concrete lesson with base-ten materials, in math centers, for small-group review, or as a quick check to see who can identify and write tens and ones independently.
