I found this link http://www.k12reader.com/subject/main-idea-worksheets/ that provides Main Idea passages and questions FOR ALL GRADE LEVELS! How stinkin' awesome is that?? I printed off four different levels of worksheets for my high, medium, low and lower students and it was amazing!
I actually used all the passages to show how main idea develops depending on difficulty. It was mainly a 'review to the low and teach to the high' moment with the low kids learning that every passage has a main idea and the high kids understanding the development of main idea.
Happy Super Bowl Sunday!
