What is a missing factor?
Factors are the numbers being multiplied. In 6 × 7 = 42, the factors are 6 and 7, and 42 is the product. A missing factor problem hides one factor: 6 × □ = 42.
Solving it is the same as dividing: 6 × □ = 42 means 42 ÷ 6 = □. That makes this game good practice for division facts too.
