This is a powerpoint I used for a lesson on idioms.

Idioms included:
"A hair-raising experience"
"In one ear and out the other"
"Lead by the nose"
"Green thumb"
"A hole in the head"
"Pain in the neck"
"Break the ice"

The rest of the lesson we did different icebreaker games that are popular in the U.S.: the Human Knot, Look Up Look Down, Zip Zap Zoop, etc.
