Bill Sands had an old book on progressions for skills. I think it was called Drills for Skills. It should be available on the USECA ( Elite Coaches Association ).
Both of you GymDad's, like Geoffrey, we could probably come up with our own progression lists besides having our own skill charts for our programs. Many coaches would, could, and have and many would differ. I once saw a really cool pyramid chart of basic skills through compulsory starting off with really basic things and how they connected at a congress clinic.
Salto, which direction. Each would require different ones.
Cartwheel: hand on mat, hop both feet over panel mat. hop one foot over panel mat at a time. do same from star position and side lunge. cartwheel legs as high as hips. cartwheel vertically over mat or on ground. learn other side simultaneous or one step behind.
Side cartwheel from star or side lunge back to star. side cartwheel to landing in lunge facing opposite direction from starting position. lunge cartwheel to lunge. side/front lunge cartwheel step in/together, cartwheel step in 3 running steps back. learn round off down incline or off panel mat. round off from lunge, round off from step, round off power hurdle, round off to landing on back by pushing off and snapping feet under.
handstand snapdown/thru with spot evolve from donkey kick to handstand on floor or trampoline.
somewhere in there would be learning cartwheel from a kneeling lunge besides spotted straddle handstand in air, lean one hand off and push then transfer to other. handstand, handstand, handstand.
Now do you see how all of this stuff interconnects?
For a side aerial, you'd master the side and front cartwheel and then work one arm near and far arm cartwheel starting off with CW with one hand on top of the other. somewhere in there a dive cartwheel then doing it off a panel mat focusing on heel drive, pushing off base leg and chest down besides arm action.
BHS: jump backs on pit. learning how to squat and sit back fall to butt with butt behind knees, knees behind toes. bridge kickover off height, backbends to incline and bridge walks on wall. a cagillion handstands, arched handstand on wall-snap down to pushup. seat drops, back drop, back drop to dead man position ( straight body on tramp ). back walkovers over octagon/BHS over octagon to pushup or hollow C stand. spotted jump back to banana in air-coach spots to handstand step out and snap down. sit, jump back without arm swing to handstand with coach. bounce on tumbl-trak, jump back to portapit, bounce on tumbl-trak, jump back to handstand chest roll or front drop. spotted back handsprings with coach with full body spot, 2 hand, 1 hand, leg spot. back handspring into pit from standing on incline in pit to hands in pit body in pit, BHS from top of incline to hands at bottom of incline feet in pit.
Arabian double double? Umm, RO 1/2 turn to dive roll, then front, etc.
If you dads are really interesting, there is probably some dvd's over at Link Removed by Mas Watanabe or if you can find some of the videos by Neil Resnick or Jack Carter.
Now imagine doing that for every skill out there...
