Subtracting Decimals 1 Digit Practice Activities
Class 4 maths worksheets for subtracting one-digit decimals, with tenths, place value, alignment, and regrouping practice.
Practice that builds confidence
Understanding tenths before subtracting
These Class 4 maths worksheets help children practise subtracting decimals with one digit after the decimal point. Learners work with tenths, line up decimal points, subtract whole numbers and tenths, and check whether regrouping is needed.
The printable activities include clear vertical subtraction, mixed decimal examples, and problems that build accuracy with numbers such as 6.8 - 2.4 or 5.2 - 1.7. They are useful for revision, homework, extra practice, or small-group support.
One-digit decimals are numbers measured in tenths, so 3.6 means 3 wholes and 6 tenths. Children first need to see that subtracting 4.7 - 2.3 is like subtracting wholes from wholes and tenths from tenths. The decimal point is not a decoration; it keeps the place values in the correct columns.

Skill progression in these worksheets
The practice moves from straightforward subtraction without regrouping to examples where a whole must be regrouped into 10 tenths. For example, in 5.2 - 1.8, children cannot subtract 8 tenths from 2 tenths until 1 whole is changed into 10 tenths. This builds confidence with both place value and the written subtraction method.
A simple parent routine
At home, ask your child to read each number aloud as wholes and tenths before writing the answer. Use a quick routine: circle the decimal points, draw columns if needed, subtract the tenths, then subtract the wholes. After every few sums, ask, “Is my answer reasonable?” For 7.5 - 3.1, the answer should be a little more than 4, so 4.4 makes sense.

Classroom uses for teachers
Teachers can use these sheets during decimals revision, maths centres, remedial groups, or as independent written practice after a place-value lesson. A useful classroom follow-up is to ask pupils to sort completed questions into “no regrouping” and “regrouping” examples, then explain one solution using the words decimal point, tenths, regroup, and difference.

Common errors to watch for
Many children subtract digits without aligning decimal points, especially when the whole-number parts have different lengths. Some forget to regroup when the tenths digit on top is smaller, while others write the decimal point in the wrong place in the answer. Encourage neat columns and a final estimate to catch slips.

Why iBloom worksheets help
The worksheets focus only on subtracting decimals to one place, so children get repeated practice without distraction from unrelated decimal skills. The examples are varied enough to reveal misunderstandings, yet structured enough for Class 4 learners to notice patterns. A child-friendly strategy is: “Line up the dots, check the tenths, regroup if you must, then subtract.”
Helpful answers
Frequently asked questions
What does subtracting decimals with 1 digit mean?
It means subtracting numbers that have one digit after the decimal point, such as 6.4 - 2.1. The digit after the decimal point represents tenths.
Should children align the decimal points before subtracting?
Yes. Aligning decimal points keeps wholes under wholes and tenths under tenths, which prevents place-value mistakes in the answer.
Do these worksheets include regrouping?
Yes. The practice can include sums where the top tenths digit is smaller than the bottom tenths digit, so children need to regroup 1 whole as 10 tenths.
How can I help my child check a decimal subtraction answer?
Ask your child to estimate first or after solving. For example, 8.6 - 3.2 should be close to 5, so an answer like 5.4 is reasonable, while 54 or 0.54 is not.
Are these suitable for Class 4 decimals revision?
Yes. They focus on a Class 4 decimal skill: subtracting numbers with one decimal place using place value, correct decimal-point placement, and regrouping where needed.
