This is a great centers game where 4 children can play at once. The game is color coded (Blue, Red, Green and Black) both the game board as well as the pieces of the game. Print out on card stock and laminate if you wish. Place the Octopus boards and their respective pieces in individual envelopes to keep the games separate. You will notice that the outlines of the circles on each Octopus board are color coded to that game board as well as on each game piece the outline of the images is also color coded.
