Grades 3 & up. Wilson takes pleasure hiding in various locations in the first quadrant. Players match hiding places with ordered pairs such as (2, 5) and (4, 3), building an octopus-like pattern outward from the octomino starting board. Where?s Wilson? is self-checking! If the 44 dominoes are placed correctly, open ends of those on the octomino tracks and those yet to be played can be paired. Game variations make it possible to meet the needs of a wide range of students. For 2-4 players.
