Kids stand around parachute and hold it high above their heads (a very taut parachute is needed so have the kids take an extra step or two backwards). Number off the kids. When a number is called, those students become the mice. They must crawl under the parachute, trying to crawl out between the students still holding the chute and back under the chute as many times as they can. When you blow the whistle, students still holding the chute pull it quickly to the ground to see how many mice they can trap.
