Practice that builds confidence
Build place-value accuracy
These Grade 6 math worksheets help students strengthen decimal addition and subtraction across numbers with 0 to 6 decimal digits. Children practise lining up decimal points, regrouping carefully, subtracting from whole numbers, and handling decimals of different lengths.
The printable activities include column addition and subtraction, mental subtraction with 1 to 2 decimal digits, missing addend problems, missing minuend and subtrahend problems, and mixed practice with decimals to 2 or 3 decimal places.
Decimal addition and subtraction depend on understanding that tenths, hundredths, thousandths, and smaller decimal places must be combined with matching places. These worksheets move students from familiar 0 to 2 and 0 to 3 digit decimals into column problems with up to 6 decimal digits, so they practise accuracy without losing the meaning of the number.

Progress from straightforward to flexible problems
Students begin with direct addition and subtraction, then meet decimals of varying lengths such as 4.8 + 0.36 or 12.005 - 7.9. They learn to use placeholder zeros when helpful, especially when subtracting decimals from whole numbers such as 8 - 3.47. Missing addend, missing minuend, and missing subtrahend questions add algebraic thinking: students must decide which operation makes sense, not just follow a layout.
Parent routine for home practice
Choose one page and ask your child to read each number aloud before solving. Have them mark the decimal points in color, stack the numbers by place value, and estimate the answer first. After solving, ask: Is the answer reasonable? For a missing number problem, encourage them to write a related equation, such as missing addend = sum - known addend.

Classroom uses for teachers
Teachers can use these printables for warm-ups, small-group reteaching, homework, math centers, or exit tickets after a lesson on decimal operations. A teacher might assign mental subtraction items to build number sense, then use column subtraction with varying decimal lengths to check procedural fluency. Missing-number sets work well for partner discussion because students must explain their reasoning.

Common errors to watch for
Many Grade 6 students line up the last digits instead of the decimal points, forget to annex zeros, or misplace the decimal in the answer. In subtraction from whole numbers, they may write 8 - 3.47 as if 8 has no decimal places, instead of thinking 8.00 - 3.47. In missing subtrahend problems, some subtract in the wrong direction, so encourage them to identify the whole, the part taken away, and the difference.

Why iBloom worksheets help
iBloom practice is organized around the exact decimal skills students need: adding decimals, subtracting decimals, working with varying lengths, and solving missing-value equations. A child-friendly strategy is Align, Fill, Solve, Check: align decimals, fill empty places with zeros, solve carefully, then check with estimation or the inverse operation.
Helpful answers
Frequently asked questions
What decimal skills do these Grade 6 worksheets cover?
They cover adding and subtracting decimals with 0 to 6 decimal digits, decimals of varying lengths, subtracting decimals from whole numbers, mental subtraction, and missing addend, minuend, or subtrahend problems.
How should students line up decimals in column problems?
Students should line up the decimal points first, then match tenths with tenths, hundredths with hundredths, and so on. They can add placeholder zeros to make the columns easier to read.
Why are missing minuend and subtrahend problems included?
Missing-number subtraction problems help students understand the relationship among the starting amount, the amount taken away, and the difference instead of only following a subtraction procedure.
How can my child check decimal addition and subtraction answers?
They can estimate before solving, then use the inverse operation after solving. For example, if 9.2 - 3.75 = 5.45, they can check that 5.45 + 3.75 = 9.2.
Are these worksheets only for written column practice?
No. Some activities focus on column work, while others build mental subtraction with 1 to 2 decimal digits and reasoning with missing decimal values.
Is this grade 6 decimal addition and subtraction worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this grade 6 decimal addition and subtraction 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 grade 6 decimal addition and subtraction worksheet include answers or an answer key?
