Subtraction Up To 20 No Regrouping Practice Activities
Printable Class 2 maths worksheets for practising subtraction facts up to 20 without regrouping or borrowing.
Practice that builds confidence
Building subtraction within 20
These Class 2 subtraction worksheets help children subtract numbers up to 20 where no regrouping is needed. Learners practise taking away from numbers such as 12, 15, 18 and 20, building accuracy with simple differences before moving to harder subtraction.
The printable activities include clear number sentences, vertical subtraction, missing-number questions and visual practice using familiar representations. They are useful for homework, revision, maths centres and extra support for children who need confidence with subtraction within 20.
Subtraction up to 20 no regrouping is an important Class 2 maths skill because children learn to remove a smaller number without needing to borrow from the tens place. Problems may include facts such as 16 - 3, 19 - 7 or 20 - 10. The focus is on understanding “take away”, “left”, “difference” and “minus”, not just memorising answers.
How the practice progresses
The worksheets move from straightforward take-away questions to mixed formats. Children may solve horizontal sums, vertical sums and missing-number problems such as 14 - __ = 10. Visual models like counters, dots or number lines support children who still need to see what is being removed. As the practice becomes less visual, children begin to rely on mental maths and known facts.
A simple parent routine
At home, start with 5 quick oral questions using objects: “You have 17 buttons and give away 4. How many are left?” Then let the child complete one worksheet section independently. Ask them to explain one answer aloud using a number line, fingers or objects. End by checking errors together and rewriting one tricky problem neatly, with the minus sign and equals sign in the correct place.
Classroom uses for teachers
Teachers can use these printables for morning work, small-group remediation, maths centres or quick revision after teaching subtraction within 20. They also work well for differentiating practice: some children can use counters or ten-frames, while others solve mentally and check with inverse addition, such as confirming 13 - 5 = 8 by thinking 8 + 5 = 13.
Common errors to watch for
Children sometimes add instead of subtracting, count the starting number again when counting back, or reverse the order of numbers in a vertical layout. In no-regrouping questions, remind them that the larger starting number stays first. Neat alignment is especially helpful when a problem is written vertically, even within 20.

Helpful answers
Frequently asked questions
What does subtraction up to 20 with no regrouping mean?
It means children subtract from numbers no greater than 20, and the questions are chosen so they do not need to borrow or regroup from the tens place.
Are these worksheets suitable for Class 2 maths revision?
Yes. They are designed for Class 2 children who are practising subtraction within 20, especially before moving on to subtraction with borrowing.
How can my child check answers in these subtraction sums?
A useful check is inverse addition. For example, after solving 15 - 6 = 9, the child can check that 9 + 6 = 15.
Should children use fingers or counters for these worksheets?
Yes, if needed. Fingers, counters, dots and number lines help children understand the take-away action before they solve the same type of sums mentally.
What mistakes are common in subtraction within 20?
Common mistakes include adding instead of subtracting, counting back incorrectly, writing the numbers in the wrong order and rushing through missing-number questions.
