The $50 Imaginext Apptivity Fortress from Fisher-Price would be fun for any kid. But adding in an iPad makes it irresistible. When you put the iPad in, it becomes a whole different game because you are actually playing video games in conjunction with the fortress. ShopSmart says it's a terrific choice.
Classic toys such as Barbie have integrated LED technology, bringing her little black dress to a whole new level. Young designers pick colors and animate their creations. Barbie and her digital dress cost $50.
Another kid favorite is the LittleBits kit, a box of magnetized electronic modules that let you build a working circuit. The base kit, at 100 dollars, contains a lot of inspiration.
A really good science book becomes a really great interactive science book when you download amazing animations on your smart phone. And at $20, the Interactive Planets 3D from Popar brings the solar system alive.
