Hi,
Here's two "Price is Right" games I downloaded off of Mediafire. It's basically the guessing game that is described in Period 1... but I'm using it for Period 2.
I like the PPT with the Korean won because it's more realistic. And having a bonus question for the team with the closest price is an excellent idea. Though I'm going to change the pictures to more Korean stuff like Kimbap is W2,500, a cellphone is W50,000, a Maltese dog at Emart is W450,000, etc...
Before starting the game, I was planning on reviewing big numbers by writing them on the board and having students raise their hand with the answer.
