Summer Exploration

I'm debating teaching a Summer Exploration course.  Here's why:

1. I'll be paid - and JJ is off during June.
2. It's from 8-12 Monday - Thursday.
3. Class size is limited to 16.
4. It's flexible - could be a one, two or three week course, or I could do one session three times (each one week long), three different courses, etc.
5. And I get to pick the topic, make the plans, have access to technology and a budget.

Sounds pretty ideal, right?  But what to do?  Hmmm... here're some ideas I've brainstormed:

1. Teaching History with American Girls (there is actually a teacher's resource book for this very thing, but it is ... ugh... out of print.  I did find one on Amazon)
2. Spanish -with a podcast project? --- using lessons from my previous foreign language days 
3. French -with a book project? --- using lessons from my previous foreign language days
4. German -with a body outline project? --- wow, that foreign language gig was pretty useful!
5. Something with remedial reading --- readers' theater, literature circles, book boxes, readers' workshop, etc.
6. Something with remedial math --- file folder games, computer games, mathsafari, etc.
7. Arts and Crafts --- I have three books devoted to this already from my summer babysitting days!  : )

What do you think?  One thing I think for sure - I'd want to do the same week-long course three times.  Why reinvent the wheel, right?  Plus, by week three, I will have that unit DOWN.  : )  Poor week 1 kids...
