This is a very fun activity for all levels. The teacher prints off the four options for students (me gusta, no me gusta, me gusta mucho, and no me gusta nada) and posts them around the room.
Then the teacher reads out a ¿Te gusta? question and the students stand next to their answer.
Included are the signs, directions for the teacher, and 13 sample questions (although you can always add more or change them depending on the vocabulary you are working in).
I've done this activity a lot and the high school students seem to enjoy it just as much as the elementary students!
