**Find the missing prime factor tips**

**Prime number**- a number that only has two factors (1 and itself; For example, 3 only has two factors 1 x 3. Therefore, 3 is a prime number).

**Composite number**- a number that has more than two factors.

**Factor Tree**- A diagram that helps find prime factors of a product.

“**1” is neither prime nor composite**

**Review how to use factor trees**:

Reminder: There can be various ways to begin the factor tree, as long as children get the same result of prime numbers at the end of the tree (highlighted numbers).
