I use this activity with my sheltered U.S. Government class (mixed ESOL levels 1-5) as a way to develop writing skills using academic vocabulary.
You can purchase dice very inexpensively at Target, Wal-Mart, etc. to use. Rolling the dice somehow makes the activity more engaging/ fun for students. I use it as a warm-up, closure activity, and/or as a station to review. If you use it as a station, you'll only need two dice! :)
