What children learn
These Class 6 decimal addition and subtraction worksheets help children practise lining up place values, adding and subtracting decimal numbers, and checking whether answers are reasonable. Activities include decimals with 0 to 6 decimal digits, varying lengths, and whole numbers mixed with decimal values.
The printable practice moves from simple 0–2 digit decimal sums to column addition and subtraction, missing addends, missing minuends or subtrahends, and mental subtraction with 1–2 decimal digits. Children build accuracy with tenths, hundredths, thousandths, and beyond.
Children strengthen the idea that a decimal point separates whole numbers from parts of a whole. In addition and subtraction, they learn that tenths must be combined with tenths, hundredths with hundredths, and so on. The worksheets include adding decimals with 0–3 digits, adding decimals of varying lengths, and adding decimals in columns up to 6 decimal digits.
Progression across the practice
The set begins with shorter calculations such as decimals with 0–2 decimal digits, then extends to longer column work. Subtraction practice includes decimals of varying lengths, subtracting decimals from whole numbers with 1–3 decimal digits, and column subtraction up to 6 decimal digits. Missing addend, missing minuend, and missing subtrahend questions encourage children to think about inverse operations instead of only following a procedure.
A simple parent routine
At home, ask your child to read each number aloud using place value language before calculating. For example, they can say “3 and 45 hundredths” rather than only “three point four five”. Let them rewrite one or two problems in columns, align the decimal points, fill empty places with zeroes where useful, and estimate the answer before solving. After the calculation, ask, “Is the answer a little bigger or smaller than the starting number?”
Classroom uses for teachers
Teachers can use these printables for concept revision, maths centres, independent seatwork, or short skill checks after teaching decimal operations. Mixed-length problems are useful for spotting whether learners align digits by the right edge instead of by place value. Missing number sheets work well for pair discussion because children must explain which operation helps find the unknown value.
Common errors to watch for
Many Class 6 learners subtract 4.2 from 10 by writing 4.2 directly under the 10 without using 10.0 or 10.000. Others add digits from right to left without aligning decimal points, or forget to regroup across the decimal point. Mental subtraction questions may also lead to answers with misplaced decimal points, especially when moving between tenths and hundredths.

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 iBloom sequence gives repeated, focused practice while varying the format enough to prevent memorised steps. Children see column calculations, varying decimal lengths, whole-number subtraction, and missing-value questions together, so they connect procedure with meaning. A child-friendly strategy is: line up the points, add helpful zeroes, calculate by place, and check with an estimate.
Helpful answers
Frequently asked questions
What decimal skills are covered in these Class 6 worksheets?
They cover adding decimals, subtracting decimals, column calculations up to 6 decimal digits, subtracting from whole numbers, mental subtraction with 1–2 decimal digits, and missing addend, minuend, or subtrahend problems.
Why do some questions use decimals of different lengths?
Varying lengths help children focus on place value instead of the number of digits. For example, 2.5 and 2.500 have the same value, but children must align the decimal points correctly when calculating.
How can my child subtract a decimal from a whole number?
Ask them to write the whole number with a decimal point and helpful zeroes, such as 8 as 8.000, then subtract by place value. This makes regrouping clearer.
Are the missing number questions useful for revision?
Yes. Missing addend and missing minuend or subtrahend questions make children use inverse operations, so they understand the relationship between addition and subtraction.
What is the best way to check decimal addition or subtraction answers?
Children should first estimate, then calculate, and finally compare the answer with the estimate. They can also use the inverse operation, such as adding back after a subtraction.
Is this Class 6 decimals addition subtraction worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 6 decimals addition subtraction worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
