Subtract Vertical Within 20 No Regrouping Practice Activities
Printable kindergarten subtraction worksheets for vertical subtraction within 20, with no regrouping or borrowing required.
Practice that builds confidence
What children learn
These printable kindergarten subtraction worksheets help children practice taking away in a vertical format with numbers up to 20. Every problem is set up without regrouping, so learners can focus on reading the top and bottom numbers, subtracting accurately, and writing the answer in the correct place.
Activities move from simple one-digit facts to teen-number minuends, using clear columns and plenty of practice space. They are a good fit after children understand subtraction with objects, pictures, or number lines and are ready to record equations more neatly.
Children practice vertical subtraction within 20, such as 9 - 4, 14 - 3, or 18 - 12. The main skill is not borrowing; it is understanding how a subtraction sentence looks when stacked. Learners read the top number as the starting amount, the bottom number as the amount taken away, and the answer as the difference.
Building from objects to columns
Before written practice, children may count counters, fingers, cubes, or drawings. These worksheets help connect that concrete idea to a neat written layout. In teen-number examples, children see that the ones digits line up under each other, which prepares them for later place value work without making the page too advanced.
A simple parent routine
Choose a small group of problems and read one aloud: “Seventeen take away five.” Ask your child to point to 17, cover or cross out 5 imaginary objects, then write 12. If a problem feels tricky, let them draw quick dots beside it. End by asking them to explain one answer using the words subtract, take away, and difference.
Classroom uses for teachers
Teachers can use these pages for morning work, small-group subtraction review, math centers, or independent practice after a hands-on lesson. They also work well for checking whether children can keep digits aligned in a vertical format, especially when a teen number is on top and a one-digit number is underneath.
Common errors to watch for
Some children subtract upward, reverse the numbers, or write the answer in the wrong column. Others treat 14 - 2 as 4 - 2 and forget the teen value. Encourage them to say the whole top number first and to check that the answer is smaller than the starting number unless subtracting zero.

Why iBloom worksheets help
The pages keep the numbers within 20 and avoid regrouping so children can practice one clear idea at a time. A child-friendly strategy is: “Start at the top, take away the bottom, write what is left.” This repeated structure builds confidence before children meet horizontal and vertical subtraction with larger numbers.
Helpful answers
Frequently asked questions
What does no regrouping mean in these subtraction worksheets?
No regrouping means children do not need to borrow from a tens place. Each problem can be solved by taking away the bottom number from the top number directly.
Are these worksheets suitable for preschool or kindergarten?
They are best for kindergarten children who already understand simple take-away situations. Advanced preschoolers may use them with counters or adult guidance.
Should children solve these problems mentally or with objects?
Either is fine. If a child is still developing subtraction fluency, counters, fingers, or quick dots can help them connect the vertical equation to a real take-away action.
Why are the subtraction problems written vertically?
Vertical layout helps children learn to line up numbers, write answers neatly, and prepare for later column subtraction with larger numbers.
What should I do if my child subtracts the top number from the bottom number?
Have your child touch the top number first and say, “This is what I start with.” Then touch the bottom number and say, “This is what I take away.” Repeating that language helps prevent reversals.
