This block set includes 12 Pinewood pieces that include all the planets in our solar system, the Sun, 2 astronauts (male and female) and 1 rocket. Illustrations are printed on both sides of each piece and include labels with the name of the planet. Ideal for role-playing and storytelling, children will develop their social and emotional intelligence as they explore space. This set is an ideal resource to introduce facts about the planets and our solar system. Fine motor skills are developed as children grasp the hand-sized blocks and stand them up. Made with New Zealand Pine, the pieces are 0.8" thick so they stand on their own. The double-sided pieces are printed using heat transfer technology and coated with a non-toxic, matte varnish for durability. Sizes of planets: 4.7" - 1.6" dia. All blocks: 0.8"D. For ages 24m+.
