I didn't really have a theme for my classroom this year; I just wanted a few of my favorite things. The corner cabinet was purchased at a used furniture store and filled with my science and history stuff. I hung the jellyfish from old bicycles wheels I found in someone's trash and purchased all the supplies to make them at thrift stores.
The super intelligent students aren't the ones who get the good grades. The ones who work the hardest do.
Above, American history stuff and below, a ribbon valance on my one window. (My classroom is in the basement.)
The salmon mobile was purchased when I was in Alaska.
