Decimals Worksheets — Grade 5 & 6Free Printable PDF · CBSE Class 5–6

Decimals are fractions in disguise — every decimal is a fraction with a denominator that is a power of 10. Children who see this connection understand decimal rules instead of memorising them.

Fractions in a different uniform

Decimals are not a new topic —
they are fractions with base-10 denominators.

Children who understand that 0.47 = 47/100 never need to memorise a separate set of decimal rules. The skills they already have from fractions transfer directly. These worksheets build both the procedural skill and the conceptual connection.

📍

Place value and comparison

Reading and writing decimals up to 3 places, ordering them correctly, and understanding that 0.9 > 0.19 (not the other way round). Easy difficulty worksheets focus here.

➕

Addition and subtraction

Aligning decimal points, adding trailing zeros, and computing correctly. Medium worksheets include unlike-length decimals (3.4 + 0.567) that require careful column alignment.

✖️

Multiplication (Class 6)

Multiplying decimals by whole numbers and by powers of 10, with place-value reasoning as the check. Hard worksheets include multiplication and simple division of decimals.

Where decimals connect to real life

Every price tag, measurement, and scientific value uses decimals. The Class 5–6 decimal curriculum is not abstract — it is the mathematical foundation for reading a ruler, calculating a bill, and understanding any measurement that involves fractions of a unit. Children who are comfortable with decimal place value navigate these contexts without effort.

FAQ

Decimals worksheets — what parents ask

Every decimal is a fraction with a denominator that is a power of 10. 0.3 = 3/10. 0.47 = 47/100. 0.125 = 125/1000. Children who see this connection understand why decimal rules work, rather than memorising them separately from fraction rules. CBSE Class 5 introduces decimals as an extension of fractions — the link is explicit in the curriculum, but often lost in practice.
Adding without aligning decimal points causes digit errors — tenths get added to hundredths, giving a wrong answer. The decimal point marks the boundary between whole and fractional parts. Adding trailing zeros first (3.4 + 0.56 becomes 3.40 + 0.56) fills every column so alignment is visual and errors become obvious.
Writing 0.19 > 0.9 because 19 > 9. The fix: compare place by place from left to right. 0.9 = 0.90. In the tenths place: 9 > 1. So 0.9 > 0.19. The digit count does not determine size — the place value of each digit does. Medium difficulty worksheets include ordering problems that specifically target this misconception.
Class 5 covers reading, writing, comparing and basic addition and subtraction of decimals up to 2 decimal places. Class 6 extends to multiplication of decimals by whole numbers and powers of 10, and division of a decimal by a whole number. Easy difficulty worksheets align with Class 5 scope; medium and hard difficulty worksheets introduce Class 6 multiplication and division operations.
Because our number system is base-10. Each place value position is 10 times the position to its right. Moving the decimal one place right multiplies by 10 (3.4 → 34.0). Moving it left divides by 10 (3.4 → 0.34). This is a consequence of how place value works, not a trick — understanding it means you never need to memorise the rule separately for each power of 10.
Count the total decimal places in the factors and verify the answer has the same number. 0.4 × 0.3: one decimal place plus one decimal place = two decimal places, so the answer must be 0.12, not 1.2 or 0.012. This quick check catches the most common error in decimal multiplication — misplacing the decimal point — before the answer is written.

Decimals — the number system skill that connects fractions to measurement.
