I usually do warmup with my students. Here are some ideas..
1. Hokey Pokey (about body parts)
2. Ten Green Bottles (numbers)
3. Macarena (number 1-16)
4. Rock Around the Clock (Time)
5. Penguin Dance (Left, Right, Go, Turnaround)
6. Head shoulders knees and toes (Body)
You can search for dance steps on youtube, or u can look at my blog for some of the dances that I have choreograph. I hope that helps.
