I used this with my 1st - 5th grade (mainly early grade) classes to show them the various features that a computer has and what each button can do. To make a poster out of it, I suggest buying it, printing it out in color, and then use a scanner and print it out via poster maker. I had a 36 x 36inch poster of this in my room and it showed well. The colored copy is available for purchase as well.
