Subtracting Decimals In Columns Practice Activities
Class 4 maths worksheets for practising subtraction of decimal numbers in columns with correct place value, regrouping, and decimal point alignment.
Practice that builds confidence
Understanding column subtraction with decimals
These Class 4 maths worksheets help children practise subtracting decimal numbers in columns. Learners focus on lining up decimal points, subtracting tenths and hundredths, and regrouping when a digit cannot be subtracted directly.
The printable activities include carefully arranged vertical subtraction problems, with space for working and checking. Children build accuracy with decimal place value while gaining confidence in written subtraction.
Subtracting decimals in columns is very similar to subtracting whole numbers, but the decimal point controls the place value. In Class 4, children need repeated practice seeing that tenths subtract from tenths and hundredths subtract from hundredths. A problem such as 8.45 − 3.12 works smoothly only when the digits are written in the correct columns.
Progression in the worksheets
The practice can begin with simple decimals where no regrouping is needed, then move to questions where children must borrow across the decimal places. Some problems may need a zero as a placeholder, such as writing 6.5 as 6.50 before subtracting 2.75. This helps learners understand that adding a zero after the decimal does not change the value, but it can make the written method clearer.
Common errors to watch for
Many mistakes happen before the subtraction even begins. Children may align the numbers by the right edge instead of aligning decimal points, forget to write the decimal point in the answer, or borrow from the wrong place. Another common error is treating 4.2 and 4.20 as different values. Encourage children to read the number aloud using place-value words, such as “four and two tenths,” before calculating.
A simple parent routine
At home, ask your child to copy one problem neatly, circle the decimal points, and draw faint vertical place-value columns. After solving, have them estimate the answer using nearby whole numbers to see if it is reasonable. For example, 9.8 − 4.3 should be close to 10 − 4, so an answer near 5 makes sense.
Classroom use for teachers
Teachers can use these worksheets for independent maths practice, small-group remediation, homework, or revision after introducing decimal place value. They also work well for quick error analysis: display a solved problem with misaligned decimals and let students explain what went wrong.

Helpful answers
Frequently asked questions
What does subtracting decimals in columns mean?
It means writing decimal numbers one below the other and subtracting by place value. The decimal points must be aligned so tenths, hundredths, and whole-number places are subtracted correctly.
Why is decimal point alignment important?
If the decimal points are not aligned, the digits fall into the wrong place-value columns. This can make a child subtract tenths from ones or hundredths from tenths, leading to an incorrect answer.
Should Class 4 children use zeros when subtracting decimals?
Yes, when helpful. For example, 7.6 can be written as 7.60 before subtracting 3.45. The zero does not change the value, but it makes the hundredths column clear.
How can my child check a decimal subtraction answer?
They can estimate with nearby whole numbers first, then add the difference back to the smaller number. If the sum matches the starting number, the subtraction is likely correct.
What mistakes should I look for in this worksheet practice?
Watch for misaligned decimal points, missing decimal points in answers, borrowing from the wrong column, and confusion between values such as 5.4 and 5.40.
