My co-teacher wanted me to go over the vocab in the "Special Lesson." Since most of it is easy I decided to make a game out of it. I showed them four pictures of the word. If they knew the word in English I gave them two stickers, if no one knew the word in English I would give them a sticker for the Korean equivalent. Then I had them complete a worksheet with all of the words. The worksheet's main purpose was to see if they could follow all of the instructions. Unsurprisingly the answer is no. To go over the answers I made it a Jeopardy game. They won't finish the last game but it keeps them busy.
I hope this helps!
