This was a fun activity. I made a comic (right) using comic strip generator. It was pretty easy to do, very user friendly.
I also made a fake magazine cover (below) using fake magazine cover, featuring my hubby and manx. The magazine cover was fun -- but confusing. I had to try it a few times before being successful. It could certainly be more user friendly.
I am a little shy to use most of these generators in the classroom, simply because many had inappropriate images available (nude woman, etc.) And I know many of my 5th graders would go right to those images, unless they were blocked. Not that I'm for blocking everything! I think trading cards could be used for fun vocabulary reinforcement.
