Whether they're six or sixteen, if you want your kids learning over summer, it helps to be sneaky and make sure that toy you offer up appears more fun than educational.

Take Crayon Physics, for example, which requires certain science skills to be mastered as the child moves up in levels.

"It feels like it's all just a little game that any kid would play," said one teenager.

Even younger kids can up their IQ’s, says Toy Insider mom Laurie Schacht. She looks to the Leap Pad by Leap Frog, and it's new e-books as an example.

"Their progress is actually assessed as they go through different activities and different games and the books will auto adjust to their level," said Schacht.

If you're worried about too much computer time, the Kurio Tablet comes loaded with controls that limit access and minutes and can be set for up to eight different people.

A new option that may amaze your kids: augmented reality. You'll all have a hard time shutting down the new Animal Planet game.

"They can watch a 3D version of behavior of in the habitat. Then, they can go in the library. They can get all kind of facts about the animal," said Schacht.

"I learned that the Bengal tiger can be three to five feet tall and they can weigh up to 300 pounds," explained 12-year-old Mackenzie Stulack.

Getting the kids up and moving matters to moms, too.

“An active body leads to an active mind,” said Schacht.

The PlasmaCar provides 360 degrees of fun and the Descender puts a different spin on a skateboard. But the Rockboard Scooter really gets them going.

"It is a scooter, but with a platform that you actually have to pedal forwards and backwards," explained Schacht.

Some other outdoor fun that's a little more cerebral: There's the Green Thumb Garden set and Growems Garden in a box.  Kids can even build a solar energy device.

Do you have a history buff in the making? The Kreo Battleship Missouri, which survived three wars, transports kids back in time.

"They're going to learn. They're going to have fun, and they're going to role-play," said Schacht.

The game Suspend is the sneakiest teaching toy of all, requiring a steady hand and strategic mind. Schacht says it teaches kids about cause and effect and balance.
