Enhance Reading Comprehension with This Free, Fun Internet Game

I'm presently working on a writing a book entitled, Visualization for Education.  While conducting research, I came across a really cool game and website.  This website was created by a nonprofit organization, The PGF Learning Portal.  They have created some very engaging and creative tools to assist young learners.  My favorite activity helps to improve sequential processing and reading comprehension.  Students put comic book images in the correct sequence and then answer questions about them.  Check out some of the other games on the site too.  They all have educational value and the graphics are excellent.
