My SPY/Detective Theme has been off to a great start so far. I wanted to add some pictures of our classroom door, now that the students have finished it. I sent home a note explaining how they are each on of my clues to a successful school year, and the upper portion of a question mark for them to decorate with clues of who they are. Once they brought them back I hung them up and then we guessed who they belonged to. Once we made the correct guess I added the bottom portion of the question mark (them with a mask on).
They LOVE looking at this. We also use it as an I SPY transition as we wait for students to line up. :)
