I can take 32 students to a field trip, I have 120 students total. I can not take one class a day for four days. I cannot somehow rotate the classes so that all classes come one day and we rotate throughout (because the field trip is a half day). Any other suggestions? Or suggestions on how to pick the 32 kids? I've thought about giving all kids permission slip forms and the first 32 to give it back get to go. Or give it to the top 32 kids. Or give it to the top 10 kids in each class and whoever brings it back first can go. Or I don't know. Thoughts?
