Okay, maybe they're not quite guaranteeing they can help a preschooler master a mathematical concept that stumps more than a few grown-ups. What Kid O does say is that the Exploring Fractions toy "challenges children to explore fractions and math concepts using a tactile approach to learning."
Made of sustainable German beechwood with silkscreened colors, the Kid O is definitely pleasing to see and touch. If it's possible for any toy to make fractions fun, we'll bet on this one.
