When you get ready to hand out a new piece of music, especially a contest piece, make a Song Elements Sheet.
Here is an example one I made (This is just the:
Now, when we start to learn the piece, I don't have to work with an individual section, I can have the whole band play each part, before we sight read the actually piece.
This offers huge advantages:
1. All students are playing the whole time.
2. Students that don't get to play the melody in the song, still get to play it. This encourages some students that don't get many moving lines in band arrangements (Saxophone, low woodwinds, Tubas, etc).
3. More mileage out of a piece of music. Since all students are learning a little bit of all the parts there is more educational benefit.
This does take some time, and you have to have Music notation skills, but it can be a very handy way to help your kids grow.
