Music Symbol Centers: Symbol Stack Attack!

My 5th graders are preparing for their composition project, so we are covering all of the music symbols on my classroom rug. I posted pictures of the different centers I use last fall, so I won't post them again. But I do want to show you a new center I added this year.

It's the Symbol Stack Attack! center. I took small Dixie cups (the kind you would use in your bathroom) and drew music symbols on the outside bottom of each one. The group must name and define the symbol in order to use it to build a tower. The more cups they answer correctly, the bigger the tower they can create. Here is a picture of one group who was able to identify all 24 cups.
