Instead of food, students and faculty found signs which indicated what a dollar could purchase in the equivalent of rice or some other food product. The impact was tremendous. The donation jar quickly filled. I was surprised and pleased to learn later in the day that the donations were far greater than I had ever heard earned at any bake sale in the 25 years that I have been at my school.
Why did this succeed? I believe it was because the students tried something new. They challenged each other to look at information differently. For the rest of the day the halls were buzzing with student and faculty discussions about the impact of the "un"-bake sale.
If students are willing to try new things to teach each other, we should be at least as willing to do so as well.
