Printable Class 1 maths worksheets that help children regroup ones and tens using base ten blocks and place-value thinking.
Practice that builds confidence
What children learn in regrouping
These Class 1 regrouping worksheets help children understand how ones can be bundled into a ten, and how a ten can be broken back into ones. Using base ten blocks, children see regrouping as a real exchange, not just a written rule.
The printable activities include tens-and-ones pictures, place-value charts, drawing and counting tasks, and simple regrouping practice. They support early addition and subtraction readiness by strengthening the idea of 10 ones = 1 ten.
Regrouping is the exchange between place values. In Class 1, the most important idea is that 10 ones can be grouped to make 1 ten, and 1 ten can be ungrouped to make 10 ones. Base ten blocks make this visible: a tens rod shows one group of ten, while ones cubes show single units.
From blocks to place value
The worksheets move from concrete pictures to more organised representations. Children may count ones cubes, circle groups of 10, trade them for a tens rod, and then write the number in a tens-and-ones chart. For example, 14 is seen as 1 ten and 4 ones, not just the digits 1 and 4 placed side by side.
A simple parent routine
At home, give your child buttons, seeds, or small counters. Ask them to make a number such as 16. Let them count 10 objects, tie or circle them as one group, and leave the remaining 6 as ones. Then ask, “How many tens? How many ones?” Keep the language steady: group, regroup, ten, ones, exchange, more, fewer.
Classroom uses for teachers
Teachers can use these sheets after hands-on base ten block lessons, during maths centres, or as quick checks before moving to addition and subtraction with regrouping. They also work well for partner talk: one child explains the blocks while the other writes the tens and ones.
Common errors to watch for
Some children count the tens rod as 1 instead of 10. Others write the total number before checking leftover ones. A helpful child-friendly strategy is: “Make ten, trade ten, then count what is left.” Encourage children to touch or mark each group of 10 so they do not double-count.

Helpful answers
Frequently asked questions
What does regrouping mean in Class 1 maths?
In Class 1, regrouping usually means exchanging 10 ones for 1 ten, or breaking 1 ten into 10 ones. Children learn this with blocks and pictures before using written methods.
Do children need to know addition with carrying before these worksheets?
No. These worksheets build the place-value understanding needed before carrying. They focus on tens, ones, and the exchange of 10 ones for 1 ten.
How do base ten blocks help with regrouping?
Base ten blocks let children see that a tens rod has the same value as 10 ones cubes. This makes regrouping a visual exchange instead of a memorised rule.
What numbers are suitable for this regrouping practice?
The activities are designed for early two-digit place value, especially numbers that can be shown as tens and ones within the Class 1 level.
How can I help if my child counts a ten as only 1?
Ask your child to point to the tens rod and count it as ten ones: 1, 2, 3...10. Then repeat, “This whole rod is worth 10, so we say 1 ten.”
