There is horseback riding and even working on a farm if you are friends with someone.
Age 5-11? I wasn't the one to suggest things to the 5 kids - they came up with stuff themselves. The oldest boy loved dribbling the basketball and shooting hoops outside, and also building things. We got him electronic kits that kept him busy for over a month building a robot and a vehicle and a radio. But the rest made villages inside with sheets, umbrellas, overturned chairs, and even wooden blocks that turned into a "campfire". The dog at one point was a reindeer, at another time was an alaskan dogsled puller, at another time a horse pulling an old-fashioned buggy, etc. My husband always wanted stuff put away each night, but I found if we left it all up, one game could continue for days!
The old board-game of "Life" was full of pretending and there was much laughter.
I see a big difference between the TV-watching, video-game playing kids, and the non ones.
Oh, and then there are books!
And catching fire flies in the evenings, and caterpillars and then watching them spin cocoons, etc. We went on nature walks daily.
And we got the kids "creek shoes" and they caught stuff in the creek and they put some into a tank. That could keep them busy for days.
My husband and his dad built the kids a playhouse and even rigged it with electricity we could connect or disconnect. They spent some nights out there in it, and we used a baby monitor. The play house was up high so underneath it we could put a big hammock.
The kids helped with gardening and we grew vegetables, so early every morning the ones who liked that (the two younger ones) helped in the garden.
Doesn't sound too "wow"? By the time they were teens, their friends were quite envious and "wowed."
