Practice Decimal Operations
Master decimal place value to thousandths, rounding, comparing, and all four operations with decimals.
Decimals are everywhere in real life: money, measurements, percentages, and data. In fifth grade, students learn decimal place value to thousandths and perform all four operations with decimals. This understanding is essential for middle school math, including ratios, proportions, and algebra.
Our decimal worksheets use money as a familiar context and progress from place value through operations. The fifth grade math hub offers more resources for a complete curriculum.
Build understanding with these proven approaches
For adding and subtracting, write numbers vertically with decimal points aligned. Add zeros as placeholders. Then add or subtract as with whole numbers.
For multiplication: multiply as whole numbers, then count total decimal places in factors. Place decimal point in product with that many places.
Money is the best real-world context for decimals. $3.25 + $1.75 = $5.00. $2.50 × 3 = $7.50. $10.00 ÷ 4 = $2.50.
Decimal place value, rounding, comparing, and adding/subtracting decimals to tenths.
Adding/subtracting decimals to hundredths, multiplying decimals by whole numbers and decimals.
Dividing decimals, mixed operations, and decimal word problems. For end-of-year mastery.
For some children, the gap is not in practice — it is in the conceptual foundation that makes decimal operations make sense. If your child cannot explain decimal place value or struggles to line up decimal points when adding, worksheets alone will not bridge that gap. Our Fractions and Decimals Foundations course (grades 4-6) covers the full progression from decimal basics through operations with decimals. You can also browse all available courses and planners on the resources page.

By the end of fifth grade, students should understand decimal place value to thousandths, round decimals, compare decimals, add and subtract decimals to hundredths, multiply decimals, divide decimals by whole numbers, and solve decimal word problems.
Use a place value chart: thousands, hundreds, tens, ones, tenths, hundredths, thousandths. 0.3 is three tenths (3/10), 0.03 is three hundredths (3/100), 0.003 is three thousandths (3/1,000). Show that each place is 1/10 of the place to its left.
Line up the decimal points. Add zeros as placeholders if needed. Add or subtract as with whole numbers, then bring the decimal straight down. Emphasize that 1.5 + 2.5 = 4.0, not 3.10 or 1.52.5.
Multiply as with whole numbers (ignore decimals). Count total decimal places in both factors. Place the decimal point in the product with that many decimal places. For 1.5 × 2.5: 15 × 25 = 375. Total decimal places = 2, so 3.75.
If dividing by a decimal, multiply both divisor and dividend by a power of 10 to make the divisor a whole number. Then divide as usual. Place decimal point in quotient directly above the decimal in the dividend.
10-12 decimal problems per day is enough. Mix types: place value, rounding, comparing, operations, and word problems.
