Intelektuāla rotaļlieta Melissa & Doug

Count on this classic wooden "calculator" for years of play and learning! The solid hardwood base and frame holds 10 thick coated wires with 10 colorful wooden beads on each -- 100 beads in all. Slide the beads for a visual and hands-on way to learn numbers and math concepts and to explore patterns and colors. Fun activity ideas included!
