A few years ago, I did a poll on the meaning of the word 'turkey'. This was to demonstrate how powerful symbols are to your students and do so with an authentic use of technology to support discussion on math, language standards, and the holidays.
As a summation to
your discussion with students on symbols, idiomatic expressions, geography, farms, or another topic, post this on your class screen. The poll includes lots of definitions for the word 'turkey'. Have each student come up sometime during the day (or class) and make their choices.
