Dividing Whole Numbers By 10 100 1000 Missing Dividend Or Divisor Practice Activities
Grade 6 students solve division equations with 10, 100, and 1,000 by finding the missing dividend or divisor.
Practice that builds confidence
What students are learning
These Grade 6 math worksheets focus on dividing whole numbers by 10, 100, and 1,000 when one part of the equation is missing. Children practice using place value, powers of ten, and inverse operations to decide whether the unknown is the dividend or the divisor.
The printable activities include equation formats such as ___ ÷ 100 = 45 and 6,000 ÷ ___ = 60, with space for students to reason rather than guess. Problems build confidence with decimal division ideas while keeping the numbers and relationships easy to inspect.
This worksheet collection sits in Grade 6 Math > Decimals Division because dividing by 10, 100, and 1,000 is the place-value foundation for decimal division. Students see that each division by a power of ten shifts the value one, two, or three places smaller. They also learn that a missing number in a division equation can be found by thinking about the related multiplication fact.
How the skill progresses
Problems may ask for a missing dividend, as in ___ ÷ 10 = 72, where students multiply 72 by 10 to get 720. Other problems ask for the missing divisor, as in 8,400 ÷ ___ = 84, where students decide that 100 is the divisor. The key vocabulary is dividend, divisor, quotient, equation, place value, and power of ten. Students should connect patterns in zeros with the value change, not just cross out zeros mechanically.
A simple parent routine
Choose five problems and have your child label the known parts first: dividend, divisor, and quotient. Ask, “Is the missing number being divided, or is it doing the dividing?” If the dividend is missing, multiply the quotient by 10, 100, or 1,000. If the divisor is missing, ask which power of ten changes the dividend into the quotient. Finish by having your child read the full equation aloud to check that it makes sense.
Classroom uses
Teachers can use these printables for warm-ups before decimal division, independent practice after a mini-lesson on powers of ten, or math centers focused on equation structure. They also work well for quick error analysis: display a solved problem with a wrong missing divisor and ask students to explain the correction using place-value language.
Common errors to watch for
Some students treat every problem as “add or remove zeros,” which breaks down when decimal quotients appear later. Others confuse the missing dividend with the missing divisor and use multiplication when they should compare the dividend and quotient. Encourage students to estimate first: dividing by 100 should make a number much smaller, while finding a missing dividend should create a larger starting number.

After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The activities give repeated, focused practice without mixing in unrelated division skills. Clear equation layouts help students notice structure, and the limited divisors—10, 100, and 1,000—let them build fluency with one important idea. A child-friendly strategy is: name the parts, choose inverse multiplication or comparison, then check by dividing again.
Helpful answers
Frequently asked questions
What does it mean to find a missing dividend?
The dividend is the number being divided. In a problem like ___ ÷ 100 = 36, students use the inverse operation and multiply 36 by 100 to find the missing dividend, 3,600.
How can my child find a missing divisor?
Have your child compare the dividend and quotient. In 9,000 ÷ ___ = 9, the number was made 1,000 times smaller, so the missing divisor is 1,000.
Why are 10, 100, and 1,000 important in decimal division?
They are powers of ten, so they connect directly to place value. Understanding how numbers change when divided by them helps students divide decimals more accurately later.
Should students just cancel zeros to solve these problems?
No. Zero patterns can help, but students should explain the value change. This prevents mistakes when equations include decimal quotients or numbers that do not end in zeros.
How can these worksheets be used in a Grade 6 classroom?
They are useful for warm-ups, independent practice, small-group reteaching, math centers, or quick checks before moving into broader decimal division lessons.
