In case you have been living in a cave, Goldie Blox is "it" for girls 5-8 years old. (http://www.goldieblox.com/)
I know it is the "it" toy when my husband comes home and says we need to get this for Christmas for Z. 1st- We don't celebrate Christmas. 2nd- We are on a spending freeze for the moment.
So what is this toy exactly?
It uses a storybook, figurines, a pegboard, wheels, axles, blocks, washers, a crank, and a ribbon to teach girls about belt drives.
It will help girls improve their spatial and engineering skills while becoming better problem solvers.
I just purchased this online today and it will be interesting to see if it gets a lot of use or gets pushed aside behind the Legos and ponies.
