Decimals Expanded Notation Practice Activities
Printable Grade 5 math activities that help students write, read, and convert decimals in expanded notation using place value understanding.
Practice that builds confidence
Building from place value
These Grade 5 math worksheets focus on decimals in expanded notation, a key part of place value and rounding. Children practise breaking a decimal into the value of each digit, such as seeing 4.382 as 4 + 0.3 + 0.08 + 0.002.
The printable activities include standard-form decimals, expanded notation, place-value charts, matching tasks, and conversion practice. Students build confidence reading tenths, hundredths, and thousandths accurately before applying that understanding to rounding and comparing decimals.
Expanded notation helps fifth graders see that every digit in a decimal has a specific value. A 6 in the tenths place means 0.6, while a 6 in the thousandths place means 0.006. These worksheets move between standard form and expanded notation so students connect digits, decimal points, zeros, and place names instead of memorizing a pattern.
A simple parent routine
At home, choose one decimal from the page and ask your child to read it aloud first. Then have them underline each digit and say its value: ones, tenths, hundredths, or thousandths. Finally, write the expanded notation together and check that the parts add back to the original decimal. Use questions like, “What does the zero hold?” and “Which part is the smallest?” to strengthen reasoning.
Classroom uses for teachers
Teachers can use these printables during place value lessons, math centers, small-group review, or early-finisher practice. Matching cards and conversion problems work well for partner checks, while place-value chart items are useful for guided instruction. The activities also prepare students for rounding decimals because they must identify which digit sits in each place before deciding how a number changes.
Common errors to watch for
Students often drop zeros too quickly, confuse hundredths with thousandths, or write 0.04 as 0.4. Another common mistake is treating the decimal point as a separator instead of understanding the whole number and decimal parts together. Encourage careful place-value language and have students compare 0.7, 0.07, and 0.007 to see how the digit’s position changes its value.
Child-friendly strategy
Try the “say it, split it, check it” routine. Say the decimal in words, split it into place-value parts, then check by adding the parts mentally or with a place-value chart. For 2.305, a child can say, “2 ones, 3 tenths, 0 hundredths, 5 thousandths,” then write 2 + 0.3 + 0.005.

Why iBloom worksheets help
The iBloom practice sequence keeps the focus on understanding, not speed. Problems vary in format so children learn to recognize expanded notation in more than one way, including decimals with zeros and decimals that extend to thousandths. Clear spacing and purposeful repetition help students notice place value patterns and build accuracy step by step.
Helpful answers
Frequently asked questions
What is decimal expanded notation in Grade 5?
Decimal expanded notation shows the value of each digit in a decimal. For example, 3.472 can be written as 3 + 0.4 + 0.07 + 0.002.
Which decimal places do these worksheets practise?
The activities focus on common Grade 5 decimal place values, especially tenths, hundredths, and thousandths, with attention to zeros that affect place value.
How does expanded notation help with rounding decimals?
Before rounding, students need to identify the place of each digit. Expanded notation makes the value of each digit clear, which helps children choose the correct rounding place.
What mistakes should I look for when checking my child’s work?
Watch for confusing 0.4 and 0.04, skipping zeros in the middle of decimals, or writing the right digits in the wrong place-value positions.
Can these worksheets be used for independent practice?
Yes. Many items are suitable for independent practice after a short lesson, while place-value chart problems can also be used for guided support or small-group review.
Is this grade 5 decimals expanded notation worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this grade 5 decimals expanded notation worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
