Multiply By Whole Tens Missing Factor Practice Activities
Class 4 maths worksheets that help children find the missing factor in multiplication facts involving whole tens.
Practice that builds confidence
Understanding the missing factor
These Class 4 maths worksheets help children solve missing factor problems where one factor is a whole ten, such as 30, 40, or 70. Children practise using mental multiplication, place value, and inverse thinking to work out the unknown number.
The printable activities include equations with blanks in different positions, products linked to whole tens, and practice that encourages children to check answers by multiplying back. The focus is accuracy, flexible thinking, and confidence with multiplication patterns.
A missing factor question asks children to find the number that completes a multiplication sentence, for example, 40 × ___ = 280 or ___ × 60 = 420. In Class 4, this builds on tables knowledge and place value. Children learn that whole tens are multiples of 10, so 40 × 7 can be thought of as 4 × 7 = 28, then 28 tens = 280.
Moving from tables to mental maths
The practice progresses from familiar products to slightly less obvious ones. Children use facts such as 6 × 8 = 48 to solve 60 × 8 = 480 or 80 × 6 = 480. They also connect multiplication and division: if 30 × ___ = 210, they can think 210 ÷ 30 = 7. This makes the unknown factor feel like a logical step, not a guess.
A simple routine for parents
At home, ask your child to circle the whole-ten factor first. Then have them cover the zero, solve the related tables fact, and put the zero idea back into the product. For 70 × ___ = 560, they can think 7 × ___ = 56, so the missing number is 8. Let them say the check aloud: 70 times 8 is 560.
Classroom uses for teachers
Teachers can use these worksheets for mental multiplication practice, maths centres, quick revision after teaching multiples of 10, or small-group support. Problems with blanks on either side of the multiplication sign help children understand that factors can change order while the product stays the same.
Common errors to watch for
Some children forget that the zero represents tens and answer 80 instead of 8. Others divide by 10 too early or confuse the factor with the product. Encourage neat reading of the equation, naming the product, and checking by multiplication. A child-friendly strategy is: “Find the tens fact, solve the table fact, then check the full number.”

Helpful answers
Frequently asked questions
What does “multiply by whole tens missing factor” mean?
It means one number in a multiplication sentence is missing, and one of the known factors is a multiple of 10, such as 20, 30, 40, or 80. Children must find the number that completes the equation.
How can a Class 4 child solve 60 × ___ = 360 mentally?
They can use the related table fact: 6 × ___ = 36. Since 6 × 6 = 36, the missing factor is 6. Then they check: 60 × 6 = 360.
Do these worksheets use division as well as multiplication?
Yes, but in a mental way. Children use division thinking to find the unknown factor, such as thinking 240 ÷ 40 = 6 for 40 × ___ = 240.
What mistake should I watch for when my child solves these problems?
A common mistake is adding an extra zero to the missing factor. For example, in 50 × ___ = 300, the missing factor is 6, not 60. The answer should always be checked by multiplying back.
Are these worksheets suitable for mental maths revision?
Yes. They are designed for Class 4 mental multiplication practice and help children strengthen tables recall, place value understanding, and confidence with multiples of 10.
