Melissa & Doug Blockables are connectable, stackable, and playable! The solid wood connect-and-play building blocks are perfect manipulatives to help preschoolers two and older boost developmental skills (fine motor, problem-solving, matching, storytelling, and self-esteem), while using their imaginations and having fun. Easy-to-grasp smooth, colorful wooden blocks fit together in a snap with large connectors that even little hands can push in and pull out. An illustrated guide shows how to arrange and link the Blockables to create multi-textured "things that go" (a sailboat with felt sail, airplane with felt propeller and wings, tractor with trailer, and race car), or kids can use their imaginations to mix, match, and combine pieces to make unique creations and play their own way! Kids can easily expand their collection -- the 54-piece Vehicles Play Set is compatible with all other Blockables play sets. The packaging folds out to convert into a fun play space and pieces store in the sturdy corrugated box with a soft handle for easy cleanup and portability. Patent pending.
