This is a more open-ended set than the motorized models like Oogly Googly. Kids can build horizontally or vertically. There are sets with small gears only- a good place to start. There are also sets with large gears with optical patterns on them and other doo-dads. All in all it's a great building system that allows kids to experiment with making machines. Great for solo play as well as co-operative building.

SNAP INFO: Fitting gears together not only develops dexterity; it's a challenging way to promote problem-solving skills as kids make moving "machines." Motors can be added, but start with hand power. ACTIVITY: Play a game of "Keep It Going!" Players take turns adding one gear at a time but every gear added must connect and keep the motion going.
