I am planning on a sports theme for my 2nd grade class and have the following planned. Some are not definite, but I am tossing them around.
Reading area: Reading Zone-put goalposts
Word Wall: A "hoop"ful of words or Catch a word
Student Work: Winning Work, or Something to Cheer About, or Cheer-ful Work, or Wall of Fame
News/Weekly Info: The Dugout
Behavior: Swinging for Good Behavior
Writing: Sliding into Writing (Baseball bases with steps)
Hope this helps. Some (most) are pretty corny!
