The songs in this show are so catchy you can't help but memorize what they're teaching you after a while. This is the ultimate in educational shows. Kids not doing well with multiplication? Well, this show has at least 20 songs dealing with that. Wanna teach kids about verbs? Show them the song about that very subject matter. I would recommend this for every child, and there's even some stuff for adults, such as a song about how to succeed in the stock market.
Because of this show generations of kids learned things like multiplication facts, electricity, parts of speech (verb, etc.) and how a bill becomes a law, all to catchy jingles. Kids who were regularly exposed to this became smarter all because of it. At the same time kids were entertained. This shows what happens when educational programming is produced by someone who understands both children's educational needs and their entertainment needs. The only shortcoming with this series is that American history is only shown from the perspective of European immigrants. Beyond that, this show is top-notch. Parents should seriously consider buying the DVD for their children.
