I liked the running dictation idea that was posted earlier. I added the papers that i plan to hang around the room to the original WS doc. I went with having a really big number and then the sentences fairly small. My thinking was that this would discourage them from reading the sentences from their seat, while making it easier to find the correct number. I also plan on numbering the groups 1-12 and having them start at that sentence, to limit the number of people crowded around a single piece of paper.
WARNING
I have not taught or actually printed this yet so adjustments may need to be made to the size of the sentences.
