About this worksheet

Missing-factor problems ask students to reverse multiplication: if one factor and the product are known, what factor is missing? Third graders often try random facts rather than using the relationship between multiplication and division. This worksheet makes the relationship explicit. Students solve equations with a blank factor, use arrays to identify missing rows or columns, connect products to related division facts, and interpret equal-group word problems. Support versions use familiar products. Standard and challenge versions include larger products and closer distractors. Encourage your child to read the equation as a question: how many groups of the known factor make the product? That language keeps the answer tied to multiplication rather than guessing. The prompts ask for fact-family reasoning, not just a nearby number.

What your child will learn

  • Find an unknown factor
  • Use multiplication and division as related operations
  • Read arrays with a missing side
  • Solve equal-group unknowns

Worked example

If 6 x blank = 42, the missing factor is 7 because 6 x 7 = 42.

Common mistake

Choosing a number that is near the product instead of a factor that makes the product.

Helpful hint

Ask what number times the known factor makes the product.
