There flew a Cow
The coach and the kids forms a circle. The coach says for example. “There flew a crow”, after which everybody quickly streetches the arms into the air and make a jump. Anything can fly, are: airplanes, butterflies, swallows, etc. At one point the adult says the adult “eThere flew a cow!” (or something else that can not fly) and at this time the children must not raise their hands and give a jump. Those who make mistakes must squat until next time.
The coach can make a little break. “It flew a …. horse”, so that children can manage to concentrate. When playing with slightly older children, you can introduce that the trainer well be fooled, so he says say “there flew a … horse”, and then raise his arms in the air and jumps.
