History Index Cards
In the picture below, the students are asked to put index cards into chronological order. To describe this, I would say that it was not super difficult, but it was not easy. There was much debating. That was about where what went. This was overall rather fun, and helps us understand a little more. When my group was doing it, we did not have many problems. Mostly talking it all out. We had a few minor mess ups, but we did pretty well. Though sometimes, we had to show our teammates why their idea made no sense. For example, we thought coal came after the Permian Extinction. We also thought that bony fish came after land animals. Silly us! But when we did correct each other, we did i nicely, of course. From doing this, I learned the order of events a little better. There was almost no supervision. We had to do it ourselves. I must say, we did pretty well. Everyone did.
Be more specific about what events people were confused about.
