Subtracting Decimals 1 Digit Practice Activities
Grade 4 printable worksheets for subtracting one-digit decimals, with practice in tenths, decimal alignment, and regrouping when needed.
Practice that builds confidence
Understanding tenths
These Grade 4 decimal worksheets help children practise subtracting numbers with one digit after the decimal point. Students work with tenths, line up decimal points, subtract carefully, and check that the answer has the correct place value.
The printable activities include clear decimal subtraction problems, mixed examples with and without regrouping, and space to show work. They are useful for independent practice, review after a lesson, homework, or extra support with decimal place value.
Subtracting decimals with 1 digit is really subtracting tenths. In a problem such as 7.4 - 2.1, the 4 and 1 are tenths, while the 7 and 2 are ones. These worksheets keep the focus on one decimal place so children can strengthen the link between whole numbers, tenths, and the decimal point.
Progression of practice
Students begin by subtracting decimals that do not require regrouping, where the tenths and ones can be subtracted directly. They then meet problems such as 5.0 - 3.6, where one whole must be regrouped as 10 tenths. This progression helps children see why 5.0 is not “5 tenths,” but 5 wholes and 0 tenths.
A simple parent routine
At home, ask your child to read each number aloud before subtracting: “six and seven tenths.” Have them rewrite the problem vertically, making sure the decimal points are in a straight column. After solving, they can estimate with whole numbers to check reasonableness; for example, 8.3 - 4.9 should be close to 8 - 5.
Classroom uses
Teachers can use these pages after a mini-lesson on tenths, in math centers, as quick review, or for small-group reteaching. The problems also work well for math talks: invite students to explain whether they regrouped, where they placed the decimal point, and how they know the answer makes sense.
Common errors to watch for
Some students subtract the smaller digit from the larger digit regardless of place, turning 4.2 - 1.8 into 3.6 instead of regrouping. Others forget to align decimal points or drop the decimal point in the answer. Encourage children to write a zero when needed, as in 6.0 - 2.7, so every place is visible.

Why iBloom worksheets help
The practice is focused, uncluttered, and built around the exact Grade 4 skill of subtracting one-digit decimals. A child-friendly strategy is: line up, regroup if needed, subtract tenths, subtract ones, then check with an estimate. Repeating that routine across varied problems builds accuracy and confidence.
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 6.8 - 2.3 or 5.0 - 1.7. The digit after the decimal represents tenths.
Should my child line up the decimal points?
Yes. Lining up decimal points keeps ones under ones and tenths under tenths, which prevents many place-value errors.
Do these worksheets include regrouping?
Yes. Students practise problems both with and without regrouping, including cases where a whole is exchanged for 10 tenths.
How can my child check a decimal subtraction answer?
A quick estimate helps. Round the numbers to nearby whole numbers and check whether the answer is reasonable compared with that estimate.
What is a common mistake in this topic?
A common mistake is subtracting the smaller tenths digit from the larger one instead of regrouping. For example, 4.2 - 1.8 requires regrouping from the ones place.
Is this grade 4 subtracting decimals 1 digit worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
