I am actually doing the Marvel comics in my 4th grade classroom. My reading center is Spider Man, "Get Caught In Reading", for my reading center. Batman, "Reading Crusaders", for my Accelerated Reader board. Superman, "Super Math", for my math centers. WonderWoman, "Wonderful Writing", for writing centers. I was not able to think of any helper names but I used the MOOSE website to come up with my Homework folder which is "H.E.R.O (Have Everything Ready and Organize)"
I know this is alot but if you need any other ideas I will try to help.
Oh yeah! I had my oldest children trace the characters using the overhead and color to decorate the centers.
Oh yeah! Check out the birthday section in Walmart to help you decorate. They have both spiderman and batman.
Ok I hope this helps!
