Divide the girls into teams of three. Each pair of teams will need 6 markers (bean bags or scarves in two sets of different colours, 3 to a set) and an large scale Xs and Os board. The teams line up across from the board like in a relay race. On go, one member of each team will take their marker and run down to the board to place it. They run back to their team and tag the next girl in line. She runs down and places her marker. Repeat for the final set of girls. If there is not three in a row, then the teams take turns, sending one member to move a marker to a new position, until one team wins. If you have more then two teams, rotate teams and let them play again.
