I had the opportunity this past summer to volunteer at a school for the underprivileged. It was here that I packed backpacks full of school supplies, colored book marks, and Dr. Seuss novels for young kids to emphasize the importance of an education.
I agree with Alina below me in that the kids should be given free range to give a solution to a topic or problem. As for the materials given to the students, it really depends on the topic at hand and the age range of who is participating.
I'll be sure to share this prototype with my friends!
