Split your group into several teams. Give each team a platter and a few cans of alphabet soup, or for a less messy option,a box of Alphabits cereal. Each team must sift through the goo to spell words or make numbers.
You can give points a number of ways:

– words of three letters
– words of four letters
– words with five or more letters
– Churches can give students high points for spelling spiritual words
– the biggest word gets a lot of points
– leaders’ names get high points as well
