The company LeapFrog has a wide variety of truly excellent children's toys -- both fun and educational. Elton Billing told me about their toy for learning the multiplication table. Billing described his experience with the toy this way: "My children were able to use the device by simply exploring the controls on the product. In fact, the user guide is really only useful to keep parents distracted a few minutes so that children can learn the device without being interrupted by pesky adults. "Other important features: * It looks like a toy * It makes sound * The sound is loud enough to annoy parents if used for hours while in the family car * Two or more can use it together" Fun. self-explanatory. Educational. What else could one wish for?
