I tell my students to count loudly on the things they are supposed to play and whisper the counts of the things they don't play. This way, they are essentially playing the exercise with their voice. Also, on my more advanced students, I have them start counting what they see. For example, if they have to play something like 1_+a, 2_+a, I have them count it that way instead of counting all of 1e+a, 2e+a. They do need to have an 8th note pulse going through their head as well. Vocalizing what they play also transcribes well to playing drumset beats. I have them voice a lower pitch for bass drum and a higher one for snare. I think it works well for them in reverse, where they can hear a beat on the radio and figure out where everything is.
