The Sonic Scooter has a revolutionary design that opens a whole new window of opportunity of movement and cooperative play. Getting onto this crescent-shaped, aerodynamic Board will really excite your students! Unique tongue & groove interlocking channels are located at the front and back of each board. Simply overlap them, press down, and you've created one team board out of many seperate boards. They'll stay together firm until purposely pulled apart. Connect 2, 6, 10 or even "pivot" as one end becomes the axis and the other end moves around the center. The usable surface area between the handles are 14" wide. For preschool to 6th grade.
