Sharks and Minnows can be played outside or in a gym.
In the gym, you can use the baseline and mid court line of the basketball court. The boundaries are from sideline to sideline. If outside, you will need to draw or tape lines about 30-40ft apart. Have the group all stand on one of the lines (they will be the minnows).
Pick one kid to stand on the opposite line (they will be the shark. On you word, the minnows will try to run to the other line and avoid being tagged by the shark. The shark tries to tag as many minnows as they can. If a minnow is tagged, they turn into a shark for the next round.
