I have all sorts of blank grand staffs in my studio of varying sizes from business card sized to poster board to one grand staff that takes up the entire floor length of my foyer. By now you already know that I LOVE places like Dollar and party stores. My favorite place of all which is a few minutes from where I live that I consider a teacher's paradise is called U.S. Toys (CPToys online) right next to LaserWorld. I go in there focused on getting only one or two items that I need and end up walking out with a bag full of stuff....sigh. Sometimes, for inspiration, I just walk up and down the aisles thinking of what games I could make up with the stuff they have. This activity came from one of those such aisle walks. I saw these cool plastic party favor mazes (first picture) and at the time I knew it could be used for something musical but didn't know what. They were cheap enough so I bought them! A few weeks later the idea came to me! 
I put velcro dots on every line and space of one of my laminated poster board size grand staffs and tacked it on the wall above my electronic keyboard. Then I created a piano keyboard out of butcher paper, laminated it, and put velcro dots on every white and black note, and tacked that up as well (underneath the grand staff and above the keyboard). 
I put velcro dots on the backside of the plastic games pieces and put one set of colors on whatever lines or spaces I wanted to test my student's knowledge of. I added stems with an overhead wipe off marker that I could easily clean off with a damp paper towel when needed. I'd give my students the other set of game pieces and have them place them where they'd go on the paper keyboard. The red staff note would correspond to the key with the red game piece on it, the blue staff note would match the key with the blue game piece, and so on. You could add sharps and/or flats to the the staff notes as well. This activity is super cheap and easy to clear off and set up between lessons! As an added task, I have some of my students play the staff notes on the electronic keyboard as well for extra reinforcement.
