Build a Bug Sorter Wooden Puzzle is crawling with bugs! It's a puzzle, a stcker, a matching game, a shape sorter and counting toy - all in one toy. The 4 adorable bugs, a ladybug, a butterfly, a caterpillar, and a bee are multi-layered puzzles to teach your toddler counting, matching, sorting and stacking. Each bug on the puzzle board has 1-4 peg stackers to build up 2 matching pieces with the corresponding color and number of holes. The shape sorter is self correcting because the number of holes on the color coordinated puzzle pieces match only their specific insects. From Educational Toys Planet, this wooden bugs puzzle will introduce your toddlers to the world of logical thinking.
