I'm sure you have seen or may even have this solfege ladder in your classroom. I bought mine a few years ago from West (here's the link: Solfege Ladder ). When I received my ladder I wasn't happy with the fact that it didn't have the syllables written on each pitch in the scale. I created my own little labels to place on each card (they aren't laminated, just printed on copy paper and mounted to colored paper). I wanted to be able to easily take pitches on and off when I needed to, so I attached them using magnetic tape.
Now that I have lived with this visual for a few years, I love it! It is so great to be able to take the pitch names on and off. This seems to help students focus on the pitches in the song they are learning and visually see the steps and skips in the pattern. I have noticed that they are better able to find steps/skips on the barred instruments than if I had all of the pitches labeled.
I also make sure to always hang the scale vertically. I have seen it hung horizontally before, and while I guess this may be a great way to connect to the barred instruments, I feel it is easier to visualize up/down, high/low when the scale is placed vertically.
