This is a worksheet to accompany a paper football activity. When I was in JHS my friends and I would spend countless hours flicking paper footballs back and forth through our 'finger field-goals'. Now your kids can enjoy it too, while also practicing English! Many Japanese are not aware of the rules of American Football so it's best to do a brief intro about kicking the ball through the field-goal.
Have each student fold their own paper football (triangle). Japanese kids are really in to origami so I find paper folding activities always go over very well. It also doubles as a listening and instruction-following exercise.
Once every student has their own ball. Have them write 5 basic questions (or change it to focus on the current grammar point) and do a demonstration in front of the class with a volunteer student.
Have the student stay opposite of you and attempt to 'score' a goal. After scoring you can ask a question. 1 point if they can answer it and 2 points if they can not (encourages more difficult questions). There are two scoreboards so partners can switch once they finish.
