Divide your class into 4 teams. Each team should line up in a row. Make four sections on the chalkboard by drawing 3 vertical lines from the top to the bottom. One person from each team will compete to properly spell words that you call out. The person that finishes first and spells the word correctly will get a point for his team. The first person from each team will go to the board and then you call out a word having to do with the Olympics. They then go to the end of the line and you continue with the next set of people.
