Winning Rhythms by Edward Ayola perfects rhythmic skills for all students, all instruments. Use it in your class. Use it in private lessons. You can even use Winning Rhythms without an instrument, clapping the rhythms. Later, add the bow or fingers. As your students become more rhythmically confident, they can play the rhythm patterns with scales. In no time at all, while their rhythm improves, they'll learn scales and fingering techniques too!
