This is one game board I did that first year with my students. Without giving them any clue as to what we were doing, I had students give me simple sentences. I wrote them on the board in the order they were given to me. They could combine any two sentences that were connected to each other on the board. We ended up with some crazy sentences, but they had a lot of fun.
This isn’t really much different from any other sentence combining activity. Students got good practice with combining sentences. But it seemed much less like work and more like fun. These were adult students I was working with, but the game approach really appealed to them.
