The Melissa & Doug Deluxe Jumbo Knob Puzzle features eight familiar shapes that are brightly colored and feature bold outlines. Each puzzle piece is constructed of extra thick, durable wood, and features a jumbo wooden knob so little ones can easily grasp each shape. The geometric shapes include a circle, square, rectangle, octagon, triangle, diamond, oval, and pentagon. Each piece also has a full-color matching picture underneath it to help kids recognize the shape. Playing with the puzzle is fun and engaging for kids while they learn different shapes and colors. It also helps little ones practice eye-hand coordination, visual perception, color-recognition, memory, matching, and fine-motor skills. The wooden knob puzzle makes a great learning tool for the home as well as the classroom for hands-on, screen-free play. It makes an exceptional gift for babies and toddlers one year and older. We design every toy to the highest-quality standards, and to nurture minds and hearts.
