What Time is it Mr. Wolf

All of the students but one line up on one side of the pool with the instructor. The one student is the wolf at the other end of the pool. The students say “What time is it Mr. Wolf” who answers with a number. All of the students take that many steps. If the wolf says “lunchtime”, the students have to run back and touch the edge of the pool or else they can be caught and turned into wolves.

Note: To make sure the instructor keeps sight of all students, a student should be a wolf. The instructor can play along but must always be able to see all of the students.
