During our mythology unit, we read "The Twelve Labors of Hercules." Once we finish our mythology unit, I like to reward the kids (and myself) with a showing of the Disney movie Hercules. While watching the movie, I have my students fill out the venn diagram comparing and contrasting the story to the movie.
I have left a blank space in the part 1 directions so you can write in how many similarities and differences your kids need to find. For part 2, I usually tell my kids to find 10 gods, goddesses, creatures, etc., and I reward those who fill in all 30 boxes with candy or a few extra credit points. You'll be surprised how many boxes some kids will fill!
