According to Valtech Co., Magna-Tiles were inspired by Pythagoras of Samos (560-480 BC), an important historical mathematician. (Perhaps you recall the Pythagorean Theorem from high school.) If this lofty inspiration doesn’t impress you, perhaps the design of the magnetic tiles themselves will. While using the tiles to build various constructs, children will also be developing familiarity with geometric shapes, which will lay a strong foundation for advanced mathematics, such as geometry and calculus. This product has no equal, Michael Ziegenhagen, owner of Playmatters in Cleveland, told TDmonthly. "It's used in some schools to teach geometry and spatial reasoning," he added.

— “We sell the Magna-Tiles from Valtech really well on a consistent basis,” Kim Emigh, VP of e-commerce at Growing Tree Toys in State College, Pa., told TDmonthly of her store’s top-selling construction items in spring 2009.
