after “basic” 2 octave majors (CGDAF and Bb)

go into 2 octave major + minor, all keys, universal fingering.

when introducing universal scale fingering, provide a visual representation of patterns as well as the pitches on the staff.

then do d major scale, 1 octave in thumb position for shape/strength of hand position.

then do three/four octave, universal fingering, into thumb position.

blam!
