Publication details: Fisher-PriceDescription: This Giant Ring Stacker reaches over 14" tall when all 6 extra large colorful rings are piled onto the wobbly base. The smallest ring has swirling beads inside for extra visual and sound feedback. This toy helps strengthen gross motor stills (standing and reaching to put the rings on), fine motor skills (grasping the rings and using hand-eye coordination to put them on the center post), and cognitive skills (sorting and stacking the rings from biggest to smallest and problem-solving to get the rings onto the post). The larger size of this toy makes it more accessible for children with motor difficulties while the sound from beads in the small ring make it more interesting to children with visual impairments
