In too deep?

Sometimes when I volunteer for things I find that I'm in over my head.  I incorrectly assumed when I volunteered to teach a VBS class for our parish that I'd have 10-15 kids in my class and that I would be as easy if not easier than a regular CCD class.  I'm finding that the opposite is actually the reality.

On Sunday I'll have to head over to the parish school and transform my assigned classroom into a rainforest.  With my modest budget I needed to procure decorations and craft supplies for 5 days.  Initially I thought this would all be a piece of cake since my class size was going to be 8 or 9 kids.  Shortly after being told the size of my class, I was asked if I minded teaching all of the kids in this age group and having an assistant.  An assistant is nice to have when you're doing crafts so I agreed.  Surely I could handle 17 kids with an assistant.  The class number has now grown to 21 kids, most of them boys.  Now I'm a little concerned.  I haven't taught a class with more than 17 kids since 2000.  The jump in class size also means I need to rework several crafts to ensure I have enough to go around.

You better believe that I'll be praying that I survive this next week.  I have to admit that I'm a little nervous that I'm responsible for teaching slightly more than 1/5 of the total number of VBS campers.
