This STEM-inspired building set brings imagination to life, cube by colorful cube. Building set comes with 200 cubes cast in 10 bright colors from red & blue to black, white & brown. Following along with the included activity guide, children can tackle more than a dozen building challenges to build their own puppy pal, create a vroom-ready motorcycle, or transform cubes into a whooshing rocket ship, or make their own creations. While they build, children will also master early critical thinking & design concepts as well as strengthen their fine-motor skills. Each sturdy cube can be snapped together or apart over & over again. Building set is designed for children ages 5 & above.
