Multiply By Whole Tens Missing Factor Practice Activities
Printable Grade 4 mental multiplication practice for finding missing factors in equations with whole tens.
Practice that builds confidence
Understanding the skill
These Grade 4 worksheets help children solve missing-factor multiplication problems involving whole tens, such as __ × 40 = 280 or 60 × __ = 420. Students practise using multiplication facts, place value, and inverse operations to work mentally.
The printable activities include equation-based practice, mixed missing-factor positions, and problems that encourage children to connect tens facts with basic facts. They are designed for fluency, accuracy, and flexible thinking in mental multiplication.
Multiplying by whole tens builds on known facts. If 7 × 4 = 28, then 7 × 40 = 280 because 40 is 4 tens. Missing-factor questions ask students to reverse that thinking: in __ × 30 = 210, they can think, “What times 3 tens makes 21 tens?” The answer is 7.
Progression in the worksheets
Practice moves from familiar whole-ten equations to mixed missing-factor formats. Children may find the first factor, the second factor, or the unknown in a related multiplication sentence. The focus stays on mental strategies rather than long written methods, so students learn to use basic facts, zeros, and place-value language together.
Parent routine for home practice
Choose a small set of problems and ask your child to explain one answer out loud before writing it. For 80 × __ = 560, prompt: “Ignore the zero for a moment. What times 8 makes 56?” Then bring back the tens: 80 × 7 = 560. End by asking your child to create one similar problem for you to solve.
Classroom uses for teachers
Teachers can use these printables for warm-ups, math centers, partner checks, or quick review after lessons on mental multiplication. They also work well for small-group reteaching because each answer reveals whether a child is using multiplication facts, division reasoning, or guess-and-check.
Common errors to watch for
Some students drop or add an extra zero, such as writing 70 instead of 7 for __ × 40 = 280. Others divide by the wrong basic fact or confuse the missing factor with the product. Encourage them to read the entire equation and label the known whole ten before solving.

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
iBloom activities give focused practice on one clear Grade 4 skill: finding the missing factor when a whole ten is part of the equation. A child-friendly strategy is: cover the zero, solve the basic fact, then check the size of the product. This keeps the work mental, structured, and easy to discuss.
Helpful answers
Frequently asked questions
What does “missing factor” mean in these worksheets?
A missing factor is the unknown number in a multiplication equation, such as __ × 50 = 350. Children use the product and the known factor to find the number that makes the equation true.
How should my child solve a problem like 70 × __ = 490?
They can use the related basic fact. Since 7 × 7 = 49, then 70 × 7 = 490. The missing factor is 7.
Are these worksheets about multiplying two-digit numbers by two-digit numbers?
No. The focus is mental multiplication with whole tens and a missing factor. Problems use place-value thinking rather than the full written multiplication algorithm.
What mistake is most common with whole-ten missing factors?
Students often put an extra zero in the missing factor. For example, in __ × 30 = 180, the answer is 6, not 60, because 6 groups of 30 make 180.
Can teachers use these for quick assessment?
Yes. Because the questions isolate one skill, teachers can quickly see whether students understand basic facts, tens, and the inverse relationship between multiplication and division.
Is this Grade 4 multiply by whole tens missing factor worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Grade 4 multiply by whole tens missing factor worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this Grade 4 multiply by whole tens missing factor worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
