Practice that builds confidence
Building subtraction within 20
These Grade 1 subtraction worksheets help children subtract numbers up to 20 when no regrouping or borrowing is needed. Students practise finding what is left, comparing simple quantities, and connecting subtraction facts to addition.
The printable activities include straightforward subtraction equations, visual supports, and mixed practice that moves from supported examples to independent work. Children build confidence with teen numbers, ones, and subtraction vocabulary.
Subtraction up to 20 is a key Grade 1 skill because children begin to work with teen numbers as a ten and extra ones. In these worksheets, problems are chosen so children do not need to regroup. Examples may include facts such as 14 - 3, 18 - 6, or 20 - 10, where the ones can be subtracted directly.
From pictures to equations
Children benefit from seeing subtraction in more than one way. A worksheet may show objects crossed out, a number line jump backward, a ten-frame style arrangement, or a simple vertical or horizontal equation. This helps students understand that subtraction can mean take away, find the difference, or find the missing part.
A simple home routine
Parents can make practice more meaningful with a short routine: read the equation aloud, ask “What is the whole?” then “How many are taken away?” Let the child solve using fingers, counters, or a number line before writing the answer. After solving, have the child check by adding: if 16 - 4 = 12, then 12 + 4 should make 16.
Classroom uses
Teachers can use these pages for morning work, math centers, small-group review, homework, or quick checks after a subtraction lesson. The no-regrouping focus keeps attention on place value, subtraction language, and fact fluency rather than on the more advanced borrowing process.
Common errors to watch for
Some first graders count backward one too many or one too few because they count the starting number as a jump. Others mix up the minuend and subtrahend, especially in vertical problems. Teen numbers can also cause mistakes when a child sees 17 as “1 and 7” instead of “10 and 7.” Encourage children to circle the starting number and use clear counting jumps.

Why iBloom worksheets help
The activities are designed to progress from visual understanding to fluent written subtraction.

A child-friendly strategy is: “Start at the whole, count back the part, and land on what is left.”
Helpful answers
Frequently asked questions
What does no regrouping mean in subtraction up to 20?
It means the child can subtract without borrowing from the tens place. For example, in 17 - 5, the 7 ones are enough to subtract 5 ones.
Are these worksheets suitable for Grade 1 students who still use counters?
Yes. Children can use counters, fingers, ten-frames, or number lines while completing the problems, then gradually move toward solving mentally.
What subtraction facts are practised on this page?
The worksheets focus on subtraction within 20, including teen-number facts such as 15 - 4, 18 - 7, and 20 - 10, without regrouping.
How can my child check a subtraction answer?
Use addition to check. If the worksheet problem is 14 - 6 = 8, your child can check that 8 + 6 = 14.
Why is my child making off-by-one errors when counting back?
Many children count the starting number as the first step. Teach them to say the starting number, then make each backward jump only for the number being subtracted.
