Practice that builds confidence
Building the idea of a ten
Grade 1 children use these regrouping practice activities to see how ten ones can be traded for one ten, and how that trade changes the way a number is shown. The focus is on understanding place value with base-ten blocks before moving too quickly to written steps.
The printable worksheets include clear tens-and-ones models, drawing and counting tasks, and problems where children decide when regrouping is needed. Activities support two-digit thinking with tens rods, ones cubes, place-value language, and simple recording.
Regrouping can feel like a rule unless children first see the exchange. These Grade 1 worksheets keep the focus on base-ten blocks: 10 ones cubes become 1 tens rod, and a tens rod can be thought of as 10 ones. Children practise counting groups, naming tens and ones, and connecting a model to a two-digit number.
Moving from blocks to written work
The pages progress from visual regrouping to more symbolic recording. A child may count 13 ones, circle 10 of them, trade for a ten, and then write 1 ten and 3 ones. In addition, children look for when ones make a new ten. In subtraction readiness, they may see why a ten can be broken into ones when there are not enough ones to take away.
A simple parent routine
Use coins, buttons, or small blocks at home. Say, “Let’s make 24: 2 tens and 4 ones.” Add more ones, and when the ones reach 10, ask, “What can we trade?” Have your child physically exchange the 10 loose pieces for one group of ten, then read the new number aloud. Keep the language steady: tens, ones, regroup, trade, and value.
Classroom uses
Teachers can use these printables after hands-on base-ten block lessons, in math centers, for small-group reteaching, or as independent practice. They also work well as quick checks because the drawings show whether a child understands the regrouping action or is only copying an algorithm.
Common errors to watch for
Some children count each tens rod as 1 instead of 10. Others make a trade but forget to change the ones count, such as showing 1 ten and still keeping all 10 ones. Watch for reversed place value, too: a child may write 31 for 13 if the tens and ones are not clearly connected to the digits.

Why iBloom worksheets help
iBloom regrouping worksheets use clean base-ten representations and small steps so children can explain what changes and what stays the same. A child-friendly strategy is: “Count the ones. If you have 10, bundle them into a ten. Then count tens first and ones last.”
Helpful answers
Frequently asked questions
What does regrouping mean in Grade 1?
In Grade 1, regrouping usually means trading 10 ones for 1 ten, or understanding that 1 ten can be broken into 10 ones. Base-ten blocks make this exchange visible.
Do children need real base-ten blocks before using these worksheets?
Hands-on blocks are helpful, especially at the start. The worksheets then help children connect the physical trade to pictures, place-value labels, and written numbers.
Are these worksheets for addition with carrying?
They build the understanding behind carrying by showing how ones combine to make a new ten. The emphasis is conceptual regrouping with tens and ones, not memorizing a procedure.
How can I tell if my child understands regrouping?
Ask your child to explain the trade: “Why did 10 ones become 1 ten?” If they can count the new tens and remaining ones correctly, they are developing real place-value understanding.
What mistakes should I correct right away?
Correct counting a tens rod as 1, leaving 10 ones after making a trade, or writing digits in the wrong place. Use the words tens and ones while pointing to each part of the model.
