About Missing Factor
What this skill is
Missing factor equations present multiplication sentences with an unknown factor (e.g., 6 x _ = 42), requiring students to use division (42 / 6 = 7) or skip counting to find the missing 7.
When children learn it
Missing factor equations are taught in 3rd and 4th grade, aligned to Common Core standard 3.OA.A.4.
Teaching Tips
- Rephrase 6 x _ = 42 as 42 divided by 6 equals what.
- Skip count by the known factor until reaching the product target.
Common Mistakes
- Multiplying the two given numbers together (writing 6 x 42 = 252 for 6 x _ = 42).
- Confusing missing factors with missing products.
