Adding Tens Practice Activities
Printable math drill activities for building fluency with adding tens using place value, skip counting, and mental addition.
Practice that builds confidence
What adding tens means
These printable Adding Tens activities help children build fluency with facts such as 10 + 4, 30 + 20, and 60 + 7. They practise seeing ten as a unit, counting by tens when needed, and connecting place value to quick mental addition.
Worksheets include focused drill sets, mixed addition facts, and clear layouts for independent practice. Children strengthen accuracy with multiples of ten, add tens to one- and two-digit numbers, and learn to check whether the ones place should stay the same or change.
Adding tens is a bridge between basic addition facts and place value. Children learn that adding 10, 20, 30, or another multiple of ten changes the tens amount while the ones can often stay the same, as in 24 + 10 = 34. This helps them move beyond counting every object one by one.
How the practice can progress
Begin with simple facts such as 10 + 6 and 20 + 8 so children connect a ten with extra ones. Then move to tens plus tens, such as 40 + 30, where they combine tens as units. Finally, include facts like 53 + 20 so learners practise changing only the tens digit and reading the full number correctly.
A parent routine that works
Use a short daily routine: first count aloud by tens from 10 to 100; next solve one row of problems; then ask your child to explain two answers. A useful prompt is, “How many tens did you add?” If an answer is wrong, have the child circle the tens digit before trying again.
Classroom uses for teachers
These worksheets fit well in math centers, morning work, fluency folders, small-group review, or quick exit checks after a place value lesson. Teachers can assign an easier page for students who need counting-by-tens support and a mixed page for students ready to add tens mentally.
Common errors to watch for
Some children add to the ones place by habit, writing 34 for 30 + 4 correctly but then treating 34 + 20 as 36. Others count by ones, which slows fluency and increases mistakes. Watch for reversed digits, skipped tens in counting, and answers that change the ones digit when it should remain the same.

Answers and answer key support
After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The layouts are intentionally uncluttered so the focus stays on the addition fact. Repeated practice builds speed, while varied problem sets keep children thinking about place value rather than memorizing a single pattern. A child-friendly strategy to repeat is: “Tens jump, ones check.” Jump by tens, then check whether the ones stayed right.
Helpful answers
Frequently asked questions
What skill do these Adding Tens worksheets practise?
They practise adding 10 or other multiples of ten to numbers, including facts like 20 + 7, 40 + 30, and 53 + 20.
How can I explain adding tens without counting every number?
Show that tens are groups. For 42 + 30, add 3 tens to 4 tens to make 7 tens, while the 2 ones stay the same, so the answer is 72.
Should children memorize these facts or use place value?
Both help, but place value should come first. Understanding tens and ones makes the facts easier to remember and apply to larger numbers.
What is a common mistake when adding tens?
A common mistake is changing the ones digit unnecessarily, such as solving 26 + 10 as 27. Remind children that adding one ten changes the tens digit, not the ones digit.
How can teachers use these pages in class?
They work well for math centers, warm-ups, quick fluency checks, small-group intervention, or review after lessons on tens, ones, and skip counting.
