ID might be rough as these are not traditional bonsai material, but I saw a few there that looked alright, and I've seen some pretty nice jades and such lately, so hopefully they can be good enough to get the girls hooked on growing miniature trees.
My best guess is sedum ochroleucum, but that doesn't look quite right.

My older daughter would like to grow a broom, which I think will work, and the youngest one wants to do a double trunk, which will be trickier. Hopefully I can get that done! Work starts this weekend, and they will get to help with every step (and mis-step too).
