Subtracting Decimals 1 Digit Missing Number Practice Activities
Printable Class 4 maths worksheets for finding missing numbers in one-decimal-place subtraction using tenths, place value, and inverse operations.
Practice that builds confidence
What this skill builds
These Class 4 maths worksheets help children practise subtracting decimals with one digit after the decimal point, while finding a missing number in the equation. Learners work with tenths, compare whole-number and decimal parts, and use subtraction facts more carefully.
The printable activities include missing minuends, subtrahends, and differences, such as 7.4 - __ = 3.1 or __ - 2.6 = 5.8. Children solve by aligning decimal points, thinking in tenths, and checking answers with the related addition fact.
Subtracting decimals with one digit after the decimal point strengthens place value understanding beyond whole numbers. In these worksheets, children see that 4.7 means 4 wholes and 7 tenths, so subtraction must compare tenths with tenths and ones with ones. The missing-number format makes the work more thoughtful than simply completing a column subtraction.
Progression in the practice
Children meet equations where the answer is missing, then move to examples where the starting number or the number being subtracted is missing. A problem like 8.5 - 2.3 = __ encourages direct subtraction. A problem like __ - 1.7 = 4.2 encourages inverse thinking: 4.2 + 1.7 = 5.9. This variety helps children understand the relationship between addition and subtraction.
Parent routine at home
Ask your child to read each decimal aloud as tenths: “six point four” and also “6 wholes and 4 tenths”. Have them underline the decimal points before solving, then write a check beside each answer using the opposite operation. For example, if 9.1 - __ = 6.8, they can find 9.1 - 6.8 = 2.3, then check that 6.8 + 2.3 = 9.1.
Classroom uses for teachers
Teachers can use these sheets for maths practice after introducing decimal subtraction, for small-group support, or as independent work during revision. The missing-number questions are also useful for quick diagnostic checks because they show whether a child is applying a memorised method or actually understanding the structure of the equation.
Common errors to watch for
Some children subtract digits without aligning the decimal point, or treat 0.6 as if it were 6 ones. Others confuse the missing subtrahend with the difference. Encourage neat vertical working when needed, and remind learners that every number has a tenths place in this set.

Answers and answer key support
After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The questions are focused on one precise Class 4 decimal skill, so children get repeated practice without distraction. A helpful strategy is: “Line up, solve, reverse-check.” Line up the decimal points, solve the missing part, then check with addition or subtraction to see if the whole equation makes sense.
Helpful answers
Frequently asked questions
What does “1 digit” mean in these decimal subtraction worksheets?
It means the decimal numbers have one digit after the decimal point, such as 3.6, 8.1, or 12.4. Children mainly work with tenths.
What types of missing numbers are included?
The missing number may be the starting number, the number being subtracted, or the answer. This helps children understand the full subtraction equation, not just the final difference.
How should my child check a missing-number decimal subtraction answer?
They should use the inverse operation. For example, for 7.5 - __ = 4.2, they find 7.5 - 4.2 = 3.3 and check that 4.2 + 3.3 = 7.5.
Why is aligning decimal points important?
Aligning decimal points keeps ones under ones and tenths under tenths. Without this, children may subtract the correct digits in the wrong place value positions.
Are these worksheets suitable for revision?
Yes. They are useful after children have learnt one-decimal-place subtraction and need focused practice with missing numbers, place value, and checking their work.
Is this Class 4 subtracting decimals missing number worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 4 subtracting decimals missing number worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this Class 4 subtracting decimals missing number worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
