Hello, pixie...The following are some simple floor exercises I do with this age group:
Sit with soles of the feet together and gently press knees down. In this same position, I have them practice "poor posture" (they "slump") and then I have them sit tall with "good posture".
Sit with legs extended in front, toes pointed; bend at hips and extend body over legs, hands reaching for the toes. Repeat with flexed feet.
Sit in a straddle and stretch to either side. I then have them "walk" forward with their hands (still in the straddle) to a "pancake" position (gym term).
Lay face down on floor, lift chest, lift and support body with hands (hands face forward between ears and shoulders) and arch back (let head go back, too). I tell them to "glue" their feet together for the stretch.
Lay on back and draw knee up to chest (other leg extended on floor)
And finally, their favorite: Kitty Kats. On hands and knees, round back with head dropped, then arch back with head and chin lifted. We often "Meow" when performing this exercise...
I would be very interested in what floor "barre" exercises Wild Rose does with this age group. I'm always on the lookout for new ideas...
