I don't only teach percussion, I also teach beginning woodwinds and brass. I have found this exercise very helpful for my beginning flutes as they learn their first 5 notes, Bb-F. It is also very helpful in getting students used to the big switch between C and D.
After my students have been playing #1 for a little while, I make it a contest of who can play it the fastest. Once they are able to handle about quarter note at 120 I switch to exercise 2.
