Factorize lets students visually explore the concept of factors, and draw rectangular arrays that have products equal to the factors.

To use Factorize, determine the factors of the randomly selected number. Enter the factorizations in the text box, and click the "Enter" button. (Factorization means the two factors that produce the product in question. Use an asterisk in place of a multiplication sign.) Click "Hint" to see how many factorizations are left.
