About Missing Factor
What this skill is
A missing factor problem requires determining the unknown multiplier when one factor and the total product are known, demonstrating that division is finding an unknown factor.
When children learn it
Determining the unknown whole number in a multiplication equation is taught in 3rd grade (CCSS 3.OA.A.4) and reinforced in 4th grade.
Teaching Tips
- Reframe the problem as division: for 6 x __ = 48, say "How many 6s fit inside 48?". If they know 6 x 8 = 48, the missing number is immediately 8.
Common Mistakes
- Multiplying the two visible numbers together instead of dividing (writing 4 x 112 = 28).
- Struggling when the missing factor is in the first position (__ x 6 = 42).
- Guessing randomly rather than using inverse division.
