Rotation 6: Using a wedge and with a spot at first, they can try foward rolls with the ball if it's small enough for them to hold 1 handed. I did this once with a group of young kids at a summer camp. They hold the ball on their shoulder with the hand on the same side. The other hand they use as they normally would for a forward roll. They get it really quickly! If the ball is too big for their hand, they can hold it between their forarm and bicep with a bent arm and just keep their palm on the surface of the ball.
Great ideas. They can also roll with the ball kind of wedged in their hip. If they're really good (the older ones) they could try the roll and you gently toss the ball for them to try to catch at the end. My sisters used to compete rhythmic, so I did a few classes and have seen the compulsory routines, and I'm trying to remember the beginning skills, but I think that's how they had them do a pike roll with the ball. Another good thing you can do is "seal" rolls, start on hands and knees with the ball in front of the knees, and then they roll/rock forward over it to a seal position with the ball under their stomach.
Holding the hoop in front of them(both hands on top, it should be "flat" against them) have them jump feet in and out, swinging the hoop as they jump through. They can eventually progress to using the hoop similar to a jump rope - forwards and backwards, one foot and two. Hold hoop up. Transfer from hand to hand. Circle swing the hoop around the arm. Around the hand (should hold the hand like an L with the hoop resting inside the "corner").
Skipping, hopping, walking on toes, over/under, up/down, side. Kicks. Waltz step. Pretty arms. Bouncing the ball (similar to dribbling) as they walk. Bouncing the ball as they go in a circle (one of the compulsory routine used to have a small run on toes in a small circle while bouncing the ball if I recall correctly). Skip, bounce, skip, bounce - any pattern like that.
One thing they can do in pairs similar to the bean bag idea (but more advanced) and with hoop, is one kid can roll the hoop (standing up) and the other can stand facing the hoop and try to either knock it over (easier) or try to toss it through (hard). First I would see if they could roll it back and forth.
Regular cartwheel progressions. If they have a decent cartwheel, lay a hoop or rope down and have them do it with their hands inside. Also work cartwheel to knee. Can eventually progress to lifting hoop/rope up as they complete cartwheel.
Some of these will be too hard for some of the kids, but some of the best 5 year olds may be able to attempt them, so I included more "school age" stuff. I wouldn't work on walkovers at this point, but handstands and handstands with the legs split should be okay.
