Got this idea from another post way back. Students enjoyed it the first time so i made another one. I like to pick the most accurate for a prize each round.

Have students partner up. Give first picture to Student A. Student B cannot see the picture. Student A must explain the picture so Student B can draw it.
Describing the picture in English only. If i hear Korean i disqualify that team. Then switch to a different picture.
I judge on accuracy.
