Bajo's tipper shape sorter truck is a truly versatile toy built for fun. Sturdy and durable, it is great for pushing and pulling along the floor, filling up and emptying out, matching shapes and stacking the blocks. The shape sorter lid can also be removed allowing the truck to be loaded up with other toys. Children love the challenge of fitting shapes through a particular hole or shape. As they learn to grasp, sort and push the shapes through the holes, their fine motor and problem-solving skills, the very first steps in critical thinking, will be developing and improving.
