This is a Hammer game that I redid from the old book. Thank you to the original creator.
The way I play it is a student gets the hammer, the entire class asks, "What's this?" and the student with the hammer chooses a picture saying, "It's a _____." If they get the cry face, they hit their hand, if they get the backside of Apeach, they hit their partner's hand, if they get the other Kakao character, they hit my hand. Some play the game by hitting on the head, but I don't because no matter how many times we told them not to hit hard, they would. So I now tell him it is like a high five.
If you change some of the photos, make sure you check it because the pictures are synced with the white squares behind them.
