Query: Pleasantly surprised!!!

Even after reading the other glowing reviews for this product, I still wasn't sure that this would live up to the hype for a preschooler who knew most of the shapes. But it did! The "songs" help reinforce shapes, like heptagon vs. hexagon. My daughter is singing the songs and talking about trapezoids like it is a commonplace shape that all 3 year olds know.I bought this DVD to test it out on something my daughter basically understood before purchasing the DVDs in the series which cover new concepts for her. Needless to say, we have gotten 2 more Munchkin Math DVDs.
