HearthSong Exclusive - A perennial best-seller, our Connectagons Glow-in-the-Dark Celestial 157-Piece Set is a customer favorite because they love the skill-building benefits and open-ended creativity our wooden Connectagons offer kids and their families. Designed to be fun for one and incredible for collaborators, pull out Connectagons for your next family game night and be amazed by the free-form or geometric sculptures your family can create using the night sky inspired shapes (moons, constellations, and Earth). A great gateway to STEM (science, technology, engineering, and mathematics) play, our Connectagons are open-ended so kids can explore essential engineering and scientific principles and develop foundational skills as they play. Just because kids may not be able to verbalize concepts like gravity and the benefits and limitations of fulcrums, but they can experiment with them through play. Each slotted wooden piece of this 157-piece building set offers kids a challenge: what can I make with this? And kids rise to the challenge by creating unique pieces of art that they can disassemble, reassemble, and add to. One of the best things about Connectagons is that kids can and will return to them as the years go by. At age 4 they develop hand-eye coordination, match patterns, and shapes and at age 13 they can build intricate structures or incorporate them into their science fair exhibit. The benefits and fun of Connectagons are endless! Made of wood, these bold colored and patterned pieces are durable and safe for your children to use. Enjoy the peace of mind HearthSong toys give you knowing that we test to meet or exceed all U.S. child safety standards. Base 10"; 157 pieces included. For ages 4 and up.
