Teach for America

I got a final interview with Teach for America!! I'm excited- I wasn't sure if I would make it through because it's so selective, but I'm one step closer! For those of you who don't know, Teach for America is a program that places college grads in low-income areas around the country to teach for 2 years in some of the nation's poorest performing schools. I'm putting Denver down as my top choice of location. I'm debating on what to put down for other top areas. I want to utilize my Spanish, but that could be almost anywhere.... Just think, if I get accepted and go to Denver you could all come visit me in the snowy mountains :) 

My interview is around December 10th, and is a day long, intensive interview. Part of it is teaching a 5 minute sample lesson plan. It can be on anything... any ideas? I'd like to teach Spanish since that's my area of study, but am not sure how to do that. What could I teach in 5 minutes? I want to use the model of I teach, we do it together, then they do it alone. Ideas I've heard of are: the primary colors, fractions, greater than/less than, Lewis & Clark... it should be something fairly concrete. 

One idea is to teach 1-10 in Spanish, or the colors. I could have the "students" (fellow interviewees) repeat with me, or do some type of interactive activity... but then I need a way for them to demonstrate comprehension.

Thoughts?? I'll be practicing this on willing people over Thanksgiving and until December....
