Design Simple or Complex Walking Challenges! Brightly colored plastic components attach to each other to form a straight, winding, serpentine shape or gentle curve. Create your own design as part of gross-motor activities, or use as a border for other play programs. Pieces have a no-slip 2”W surface, measure 12”L x 7”H, and have a 6”W base. A great way to get your entire class in on the balancing fun! Construct a large, very challenging walking board, or a number of smaller, separate walking boards to accommodate a large class working in small groups.
