Subtract Vertical Within 20 No Regrouping Practice Activities
Printable early-years maths worksheets for practising vertical subtraction within 20 where no borrowing or regrouping is needed.
Practice that builds confidence
What this skill builds
These worksheets help Nursery, LKG and UKG children practise subtracting numbers within 20 in a vertical format. Each problem is arranged in columns so children can learn to subtract the ones carefully and understand that subtraction means taking away.
The printable activities include clear, child-friendly subtraction sums that do not require regrouping or borrowing. Children build confidence with small numbers, neat number writing, the minus sign, and checking that the answer is smaller than the starting number.
Vertical subtraction within 20 is an important bridge between oral counting and written maths. Children see numbers placed one below the other, read the minus sign, and subtract the bottom number from the top number. Because these sums need no regrouping, the focus stays on the basic idea of taking away, not on borrowing from the tens place.
How the practice progresses
The worksheets use numbers from 0 to 20 with answers that can be found by counting back, using fingers, or imagining objects being removed. A child may solve 9 - 4, 15 - 3, or 18 - 6 in a vertical layout. As children move through the pages, they practise lining up digits, writing answers in the correct space, and noticing that 12 - 2 is different from 2 - 12.
Parent routine at home
Sit with your child and read one sum aloud: “Sixteen take away four.” Ask them to show 16 using counters, buttons, or crayons, then move 4 away and count what remains. After a few concrete examples, let them solve the written sums. Encourage them to point to the top number first, then the bottom number, and finally write the answer neatly under the line.
Classroom uses for teachers
Teachers can use these pages for maths practice after introducing subtraction with objects or pictures. They also work well for small-group support, morning work, revision, or independent practice once children know how vertical sums are read. A teacher can model one row on the board, then ask children to complete a few sums and explain how they got their answers.
Common errors to watch for
Young learners may start from the lower number, mix up the minus sign with the plus sign, or forget to subtract and simply copy a number. Some children write the answer beside the sum instead of below the line. Gently guide them to say the subtraction sentence each time and check whether the answer makes sense.
