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 and blue to black, white and 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 and design concepts as well as strengthen their fine-motor skills. Each sturdy cube can be snapped together or apart over and over again. Building set is designed for children ages 5 and above.
