"Listen and act"

 We give the students three numbers and its number has a certain meaning: for example the number 1 means jump, number 2 means stay, number 3 means run. The instructor starts clapping the hands and suddenly says one number and the children must do the acting that corresponds to  that number. In a second level of this exercise the instructor changes the maching number - acting. The students must be very cautious not to make mistake and leave the group.  Is a very pleasant exercise  on energetic hearing.
