Here's another great manipulative available at Dollar Tree. I made these a while ago, and just recently came up with the idea to borrow some alphabet letters from a Kinder teacher friend.
The cookie pans were 2 for $1 I want to say. The black lines are made from electrical tape (and they stay down pretty well if you press hard) which was also 2 for $1 I believe.
This is such a cute way for students to practice spelling on the music staff. I've only made five, but I really need to make more.
