Monday. I'm back in School and I need a game

Start by asking about Chuseok. How many Seonpyeong did you eat? How many relatives did you meet. etc.

3rd Grade and I think I'm going to do High or Low and a guessing thing of how many pencils in their pencil boxes.

"How many pencils are in your pencil box?"
"Are there 5 pencils in your pencil box?"
"Are there 3 pencils in your pencil box?"

Other questions I can get them to ask are "How many notebooks are in your bookbag?" How many brothers do you have? How many sisters? etc.

Game:
High/Low I'll get the students to write their number on the board and the students have to guess it by asking,

"Is the number 5?"
No, the number is higher/lower.
