Subtracting Decimals Mentally 1 2 Decimal Digits Practice Activities
Class 6 printable maths practice for mentally subtracting decimals with 1 or 2 decimal digits using place value, compensation, and estimation.
Practice that builds confidence
What this skill builds
These Class 6 maths worksheets help children subtract decimals mentally when numbers have 1 or 2 decimal digits. Learners practise reading tenths and hundredths, keeping the decimal point in mind, and choosing efficient mental steps instead of writing every calculation vertically.
The printable activities include direct decimal subtraction, mixed tenths and hundredths, missing-number style questions, and quick checks that build accuracy. They are useful for the Decimals Addition Subtraction chapter when children need repeated, focused practice with mental methods.
Subtracting decimals mentally depends on strong place value. Children learn that 6.8 - 2.4 means subtracting tenths from tenths, while 5.75 - 1.20 can be viewed as 575 hundredths - 120 hundredths or as 5 rupees 75 paise - 1 rupee 20 paise. The aim is not speed alone; it is to keep the value of each digit clear while subtracting.
How the practice progresses
The worksheets move through manageable decimal differences with 1 and 2 decimal digits. Early questions may involve clear tenths, such as 9.6 - 3.2. Later items encourage mental adjustment, such as treating 8.00 - 2.75 as 8 - 3 + 0.25. Missing-number questions ask children to reason backwards, for example, “What must be subtracted from 7.45 to get 6.20?”
Parent routine at home
Use a short oral warm-up before the worksheet: say a decimal and ask your child to subtract 0.1, 0.5, 0.25, or 1.20 mentally. Then let them complete one section independently. After checking, ask them to explain two answers aloud: “Did you subtract whole numbers first, decimals first, or adjust to a friendly number?” This helps reveal whether the method is meaningful.
Classroom uses for teachers
Teachers can use these pages for maths centres, morning revision, remedial practice after decimal subtraction lessons, or exit slips. They also work well for paired checking: one child solves mentally, while the partner estimates whether the answer is reasonable before comparing.
Common errors to watch for
Some learners ignore zero placeholders, so 4.20 - 0.75 may be treated like 420 - 75 without returning to hundredths. Others line up digits in their head incorrectly or subtract the smaller digit from the larger digit in each place. Encourage estimation first: 4.20 - 0.75 is a little less than 3.50, so an answer like 3.55 is possible, but 4.55 is not.

Why iBloom worksheets help
iBloom worksheets focus on one exact sub-skill: mental subtraction of decimals with 1 or 2 decimal digits. A child-friendly strategy is “make a friendly number”: for 6.50 - 1.85, subtract 2.00 to get 4.50, then add back 0.15 to get 4.65. Repeated examples help children choose such methods confidently while still understanding tenths, hundredths, difference, and decimal point placement.
Helpful answers
Frequently asked questions
What decimal subtraction skill is practised on this page?
These worksheets focus on mentally subtracting decimals with 1 or 2 decimal digits, such as tenths and hundredths, without relying on long written working for every question.
Are these worksheets suitable for Class 6 students in India?
Yes. The language and level are designed for Class 6 maths practice, especially within the Decimals Addition Subtraction topic.
Should children solve these decimal problems entirely in their head?
They should try mental methods first, but it is fine to jot a small note, such as a friendly-number adjustment, while they are learning the strategy.
What is a good method for subtracting decimals mentally?
A useful method is compensation: subtract a nearby friendly number and adjust. For example, for 6.50 - 1.85, subtract 2.00 to get 4.50, then add back 0.15 to get 4.65.
What mistakes should I check for while marking the worksheet?
Look for misplaced decimal points, ignored zeros in hundredths, and answers that are not reasonable when estimated against the original numbers.
