Expanded Notation Practice Activities
Grade 6 printable math activities for writing whole numbers and decimals in expanded notation using place value and powers of ten.
Practice that builds confidence
What students practise
These Grade 6 math worksheets help students practise expanded notation within the Place Value topic. Children break multi-digit numbers into the value of each digit, including numbers with zeros and decimal places.
The printable activities include converting standard form to expanded notation, rebuilding numbers from expanded parts, and checking place-value reasoning with clear, age-appropriate examples.
Expanded notation shows that every digit has a value based on its position. A number such as 4,732,018 can be written as 4,000,000 + 700,000 + 30,000 + 2,000 + 10 + 8. For decimals, 6.405 becomes 6 + 0.4 + 0.005. Grade 6 students use this skill to understand large numbers, decimal numbers, and powers of ten more deeply.
Skill progression in the worksheets
The activities move from identifying the value of each digit to writing full expanded notation and then reversing the process. Students may see numbers with internal zeros, such as 50,206, where the zero places should not be written as separate addends. Decimal examples encourage careful reading of tenths, hundredths, and thousandths.
Parent practice routine
Choose one number from the worksheet and ask your child to read it aloud first. Then have them underline each nonzero digit and say its place: “7 is in the hundreds place, so it is 700.” After they write the expanded notation, ask them to add the parts mentally or with paper to confirm the original number. This quick check builds accuracy and confidence.
Classroom uses for teachers
Teachers can use these printables for place-value review, small-group reteaching, math centers, warm-ups, or exit tickets. They also work well before lessons on multiplying and dividing by powers of ten, comparing decimals, or using scientific notation, because students must attend to each digit’s position.
Common errors to watch for
Students often drop zeros that are needed inside the standard form, confuse 0.04 with 0.4, or write a digit instead of its value. Another common mistake is listing digits in order without place value, such as writing 3 + 5 + 9 for 359. Encourage students to name the place before writing the addend.

Why iBloom worksheets help
The iBloom activities focus on one precise Grade 6 place-value skill at a time, so students can practise expanded notation without unrelated distractions. A helpful strategy is: say the number, name the place, write the value, then add the parts back. This keeps the work organized and child-friendly.
Helpful answers
Frequently asked questions
What is expanded notation in Grade 6 math?
Expanded notation writes a number as the sum of the value of each digit. For example, 8,406 is 8,000 + 400 + 6, and 2.35 is 2 + 0.3 + 0.05.
Do these worksheets include decimals?
Yes. The practice can include decimal place values such as tenths, hundredths, and thousandths, helping students see how expanded notation works on both sides of the decimal point.
How should students handle zeros in expanded notation?
Students usually skip zero-value addends in expanded notation, but they must keep zeros in the standard form where they hold a place, such as the zero in 50,206.
Why is expanded notation important for sixth graders?
It strengthens place-value understanding, supports decimal accuracy, and prepares students for work with powers of ten, comparing numbers, and later scientific notation.
What is a good way to check an expanded notation answer?
Students can add all the expanded parts and compare the sum with the original number. If the total matches, the place values were likely written correctly.
Is this expanded notation worksheets grade 6 free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
