Thanks for the replies!
@Rev Rob, I am extremely lucky because my friend who I teach the lessons with sings! So last time we did some ear training. We wrote the note on the chalkboard, she played it on her violin, she sang it, and finally we had the children hum then sing the pitch. I thought it worked great because they could see, hear, and play the pitch. But they started loosing focus. So if we continue that, we will have to break them up into groups.
@ bloke, I was actually just thinking about the recorders. I think that would be our best bet in the long run. IF we split the kids up into age groups, younger and older.
@SplatterTone, that sounds like an excellent idea!!!!!
@ Nick Pierce, As far as improvisation and drumming, (etc.) I have taught the younger children the different types of claps and was thinking about enlisting a friend or two and teaching them body percussion. I think this will work well. I will definitely look into dancing as well!
Again, thanks for the replies!!!!!!!
PS: I love my job!!!! I didn't think I was a kid person at first, but as soon as I brought music into the equation, that changed! Something clicked, I feel like I connect with them now. This is extremely rewarding and I think it's a great experience for me. Especially considering I am looking into becoming a band director in the future. I think this is the first step in becoming a successful professional musician.

I don't play the tuba.
I am a tuba player.
There's a difference.
