Build is an original and innovative virtual building block activity that encourages creativity, problem solving, and ingenuity. Objects and environments can be built from design sets or free-style with numerous interchangeable shapes and blocks in a rainbow of colors. Build a doll, a truck, a farm, your dream house, and more! We know one teacher who uses Build to teach early learners about computer assisted design (CAD) software and they even use a 3D printer to make their Build designs real. So cool! Free to build, priceless to learn.
