Grippies develop sensory perception and introduce basic concepts of magnetism, geometry, and engineering through a simple system of balls and rods. Easy-to-grasp, coated rods come in two lengths and four colors each with a distinctive texture. The magnetic balls are soft, easy to cradle in the palm. Children explore, discover magnetic polarity, and connect rods and balls to create geometric shapes and build simple structures. Sort rods by length, color, and texture, make patterns combining rods and balls. The idea is children learn best by self-directed, open-ended play. Designed as the first STEM toy for toddlers, Grippies invite inclusive play with each child delighting in the process. Develops fine motor, cognitive, and social skills, creative thinking, tactile discrimination, and spatial awareness.
