**Factoring**

 * Below are several activities, games, and worksheets for students to practice factoring numbers and using a factor tree.**
 * Review with students prime and composite numbers before moving on to factor trees and independent activities.**

Common Core Standard Adressed
4.OA.4. Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite. (Students will connect this standard by finding factor pairs and multiples while using and creating factor trees).
