After reading The Hunger Games by Suzanne Collins, I wanted to devise a similar game for my students. Of course, it had to be safe and doable in a school day.
I did this activity with about 40 sophomores, with the aid of three other teachers and a couple of older students who were available that day.
The materials you'll need will be fairly simple and very inexpensive-- you will most likely have them all on hand already. If you don't, you can do this activity for well under $10, and probably under $5.
Without giving too much away, this is a live and full-scale version of the Games for students. We did it outside on a hot day, but it could easily be done in a gym or other large open space.
It involves preparation time for the students to reflect on the book and the characters and to make tokens, a live Hunger Games, and a wrap-up activity that includes a survival movie clip (available on amazon.com for $1.99, or you can show any film that involves survival), and a compare and contrast writing prompt.
Everything is very easily modifiable to fit your purposes. After doing it this past year, I will definitely modify the activity for myself, and have included those modifications in the activity.
The document includes all handouts, lists of supplies, my thoughts and notes throughout, and generally provides a detailed overview of the whole day.
We used 3.5 hours, but it could be done in a shorter timeframe.
