The must card game is pretty straight forward.
Pull a card from the pile and point to someone and say “You must ~” and read the sentence on the card.
You must clap your hands 10 times
You must sit Seiza.
You must do 2 push ups.
It’s a lot of fun especially if you have an awesome JTE willing to be apart of the fun.
For example, my student chose the JTE to “act like a cat”
Student: “Mr. JTE you must act like a cat”
JTE: “Nyan!”
Then the JTE proceeded to walk on all fours and scratch at the students.
It was a great big laugh from all the students.
