Subtracting Decimals In Columns Practice Activities
Grade 4 printable practice for subtracting decimals in vertical columns with decimal-point alignment, regrouping, and zero placeholders.
Practice that builds confidence
Understanding decimal column subtraction
These Grade 4 decimal subtraction worksheets help children practise subtracting decimal numbers written in columns. Students learn to line up decimal points, subtract digit by digit, regroup when needed, and write answers with the decimal point in the correct place.
The printable activities include clear vertical problems that build accuracy with tenths and hundredths, including examples where a zero placeholder makes the subtraction possible. They are useful for independent practice, homework, review, or small-group math support.
Subtracting decimals in columns is the same subtraction process children already know, but place value becomes especially important. In a problem such as 6.4 - 2.18, students must rewrite 6.4 as 6.40 so the tenths and hundredths places are both visible. The decimal points stay in one vertical line, and each digit is subtracted from the matching place-value column.
Skill progression in these worksheets
The practice moves children from neat alignment to more careful regrouping. Some problems subtract tenths from tenths or hundredths from hundredths, while others require borrowing across the decimal point, such as changing 5.00 into 4 ones and 10 tenths before continuing. This helps Grade 4 learners connect whole-number subtraction to decimal place value rather than treating decimals as separate rules.
A simple parent routine
At home, ask your child to read each number aloud before subtracting: “three and forty-five hundredths.” Then have them place a finger on the decimal points to check that they are lined up. For tricky problems, encourage them to add a zero at the end of a decimal when needed, such as writing 7.2 as 7.20. After solving, they can estimate first or check with addition: the difference plus the smaller number should equal the larger number.
Classroom uses for teachers
Teachers can use these printables for morning work, math centers, exit tickets, or targeted regrouping review. They also work well after a mini-lesson with base-ten blocks, money models, or place-value charts. Students who finish early can explain one solution using vocabulary such as tenths, hundredths, regroup, difference, and decimal point.
Common errors to watch for
Many mistakes come from lining up the final digits instead of the decimal points. Others happen when students forget to place the decimal point in the answer or do not add a zero placeholder before regrouping. Watch for children subtracting the smaller digit from the larger digit in each column; they need to regroup instead.

Why iBloom worksheets help
The layout gives enough structure for children to focus on accurate place-value subtraction while still requiring independent thinking. A child-friendly strategy is: “Line up, fill zeros, subtract, then check.” This short routine keeps the process memorable and builds confidence with decimal differences.
Helpful answers
Frequently asked questions
What does it mean to subtract decimals in columns?
It means writing the decimal numbers vertically so the decimal points line up, then subtracting each place-value column, such as ones, tenths, and hundredths.
Why do students add zeros when subtracting decimals?
A zero placeholder shows an empty place value. For example, 6.4 can be written as 6.40 so it can be subtracted from or regrouped with hundredths correctly.
What decimal places are most useful for Grade 4 practice?
Grade 4 students commonly practise tenths and hundredths, with problems that strengthen place-value understanding and regrouping across the decimal point.
How can my child check a decimal subtraction answer?
They can add the answer to the number that was subtracted. If the sum equals the starting number, the subtraction is likely correct.
What is the most common mistake in vertical decimal subtraction?
A frequent mistake is lining up the numbers by their last digit instead of lining up the decimal points, which puts digits in the wrong place-value columns.
