Classroom Theme

I have a confession to make.
I'm one of those teachers.
The one who picks a theme and then goes all out decorating the room to follow the theme.

This year I decided on the theme of "Knowledge is Power" and went with superheroes. I had a blast finding different ideas on Pinterest and TeachersPayTeachers. After spending about two weeks, here and there, I'm pretty much finished. There are a couple little things I want to add, but I was proud of how it looked for Open House. 

Now it is ready to be filled with 25 superheroes this week!

Do you do a theme in your classroom? If so, what did you choose for this year?
