They are many ways to practise scales. My favourite method is as follows. I set the metronome at a nice comfortable speed, 60 to the quarter note. I play the scale in quarters, then eighths, then triplets (for a two octave scale play the scale 3x in a row so that you end up on the downbeat), then sixteenths.
