Find the Missing Factor With Integers
Written by Adi Ackerman, Head Teacher
"Find the Missing Factor With Integers" is written for 6th Grade (Ages 11-12). If your student is a year younger but already steady on integers, the page still works. You may just need to read the instructions out loud. And if they are older and multiplication of integers never quite stuck, this is a short review rather than busywork.
6th grade math worksheet: find the missing factor in 24 integer products, such as (−8) times a number equals 48. Answer key included. Part of our multiplication of integers collection.
How do I use this worksheet?
Review the sign rule on Multiply and Divide Integers before the other pages. The missing factor page works well as a check that students can divide integers too, and the whole tens page stretches mental math.
What students will practice
- Students will find the missing factor in 24 integer multiplication equations.
- Students will use the sign of the product, as in (−8) times a number equals 48, to choose a sign.
- Students will work with products up to 110 in size, such as a number times (−11) equals −110.

What does this worksheet teach?
⌄
Find the missing factor in 24 integer products, such as (−8) times a number equals 48. The directions on the page read: Write the missing integer that makes each equation true. An answer key is included.
Can I use this multiplication of integers worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 6th Grade integers, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with multiplication of integers. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
What are the sign rules for multiplying integers?
⌄
Two integers with the same sign have a positive product, and two with different signs have a negative product. So (−11) × (−11) = 121 and (−11) × 9 = −99.
How do you find a missing factor with integers?
⌄
Divide the product by the known factor and use the sign rule. If (−8) times a number equals 48, the missing factor is 48 ÷ (−8) = −6.
How do you multiply integers by tens?
⌄
Multiply the nonzero digits, attach the zeros, then apply the sign rule. 70 × (−90) starts as 7 × 9 = 63, so the product is −6,300.
Is there an answer key?
⌄
Yes. All 3 multiplication of integers sheets have an answer key.
