Activities

Play: Dolphin Marco Polo

Get a group together and mark off an area about the size of a classroom. Choose one person to be the dolphin and the rest get to be fish. The dolphin has to be blindfolded, but whenever they say ‘Echo!’ any fish around them have to answer ‘Fish!’ How long does it take for the dolphin to gobble up (catch) all the fish?
