Play a board game on your smart board for EOG reveiw. Split the class into 5-6 different teams. Roll the dice on the board for all teams, choose a question. If the majority of the "teams" (3/4 or 4/5) get the problem correct, they can move that number of places. I have used white boards to record answers, then tell the students to flip them when ready to reveal the answers. There are spots that twist the game up and have players move ahead or back. There are also customized character game pieces. Completely engaging and even great for observation days.
