My mom and I (along with others I know) have been making centers out of magazines for years now. I especially like to use the Discovery magazine that Apologetics Press puts out. I would get two of each magazine - it is easier that way. You can cut out articles for the students to read and then make games to go with them. The magazines come with some games that you can just laminate and you are ready to go! Have your students use a dry erase marker and you can wipe it off easily with a wet cloth, nail polish remover or alcohol.
