This bright and colorful poster illustrates the concept of factoring numbers through the use of cartoon characters. Each block representing a prime number has some feature relating to the prime such as number of sides on the head. Others have blocks representing composite numbers. Some of the lower numbers are represented with eyeballs. Each number is different and leads to more exploration. Unfortunately, the author did not provide easy ways to navigate among the various pages associated with this poster, so we share them here.

In the Classroom
Share this online poster on your projector or interactive whiteboard during discussions of factoring numbers or composite and prime numbers. Use this poster for a fun math center! Have students find each factor or prime number representation in the cartoon characters. Challenge students to create and draw their own factoring poster then use the posters for a colorful classroom display. This is a great way to "draw in" your visual-spatial kids in math class.
At Home
Use this resource together as a visual game to review and reinforce concepts about factors and prime numbers. Encourage your middle school student to try this site on his/her own to explain the representations within the cartoon characters.
