This activity would work best as a small group activity. During my center time, we usually have 3 students per group. Having a small group will allow them to move around more and extra room to move the scarf up and down.
I found the tape mural activity to be one of the best activities. It got each student involved taking turns and creating something together. Making the wands and dancing with them was also a pretty successful EASE lesson.
I actually feel my students were able to follow the cards better than body movements. It gave them a focal point (arrow) and they were very concentrated on following the arrow.
