Tic Tac Toe Relay
Split up players into two teams. Have 4 of the players place their sticks down, in the shape of a Tic Tac Toe board. The rest of the players can place their sticks off to the side.
Set up a small "obstacle" course based on the skill you're working on (i.e. balance, edges, tight turns, etc.). On the whistle, one player from each team starts with their team object (e.g. puck, tennis ball, cone, etc) in their glove.
On the whistle, players take off through the obstacle course and place their team object on the Tic Tac Toe board. After placing their object, players race back to their line to tag the next player who then takes off, completes the skating route, and then places their object down. Teams continue to race and play a game of Tic Tac Toe until one team has won.
