To split up into groups or not split up into groups--that is the question. It's our first field trip, we're going to the zoo. I would love to stay together as a group so we can all see the same things, I can point out things for instruction with all of them--however, I have a big class this year. I wonder if they would get more out of it if we split into smaller groups. I also don't like splitting up because some parents spend an hour in the gift shop or don't bring their group back to the bus on time. I like having them all in my sight the whole time because ultimately, they are my responsibility. So what do you normally do in a field trip situation like this?
