slow down and teach

I don't know where to start with my thoughts on today's class. Not that a lot of things went wrong today, but there is just so much running through my mind about my class- how can i teach more productivly and clear, how do i know if my students are really enjoying what i am teaching them, how can i plan a shadowing day, a lot of my girls have so much potential!!!
I began teaching a new ancient style hula dance today and we did not get very far (just the first verse- four 8 counts). The dance turned out to be a little more difficult for the girls to learn then i thought it would be. I had to keep stopping, to break down the steps over and over again. I would forget that i am working with 9th grade high school students who had never danced hula before. i know that when i was learning some of these hula dances at a young age, my hula teacher moved very slow with us. however, we had time to move slow- our classes were almost two hours longs. My Samohi class in 50 minutes with many interuptions. And i only have 6 more set planned class sessions with them! I feel like i do not have enought time with them at all- once a week for 50 minutes- thats so short.
Most of the girls are really trying and i can tell they are interested in the story of the dance, at least i think they are. It just seems like i need to move slower for the girls to get it, but if we move any slower then we'll never finish the dance, and then soon the girls will get bored of the dance. i guess this is why i am scared to move slow. Maybe sometimes I just need to have those relaxed moments with my students, where we can laugh, talk about the story of the dance, and get to know one another. Little by little we will get somewhere. I just need to remember that my students and I will make it through the year growing together and learning from one another no matter what happens.
