Just because 11-year-olds are not old enough to work at "real" jobs doesn't mean they can't find ways to make money. Earning some cash when you're a kid is easier than you think. It only takes a little creativity. When kids start earning money, they also learn life lessons about saving and investing.
The old fashioned lemonade stand is the classic version that most kids are familiar with. Set yourself apart by experimenting with other products to sell at your stand. Offer beverages that are seasonably-themed. For example, if you live in an area with cold weather, set up a hot chocolate stand in the fall and winter. In the summer, sell cold iced drinks.
Ask your neighbors if they could use a hand cleaning up their house. Offer to do specific chores like vacuuming, sweeping and wiping down sinks and counters.
Raking and Shoveling
If you live somewhere where the seasons change, offer to rake your neighbors leaves or shovel their driveways. Go door-to-door and ask your neighbors if they would like to hire you. Create simple flyers on your computer and put them on your neighbors' doors.
Talk to your friends, family and neighbors to see if they need help taking care of their pets. You can take dogs for a walk, play with their cats or watch their pets while they're out of town.
Garage and Yard Sales
Gather up all of the stuff that you don't want anymore and have a garage or yard sale. Have your parents donate some of their old belongings or offer to plan and coordinate the sale for a share of the profits. Advertise by creating flyers or posting an ad online.
Tutor Other Kids
If you excel at a particular subject, talk to your friends' parents and ask if they would like to hire you as a tutor for a small fee.
Offer to run errands for your elderly neighbors. Sometimes it's hard for older people to get around, so many of them will welcome the help.
Grow Flowers and Vegetables
Grow flowers, vegetables and herbs in your yard or windowsill and sell them to people in your neighborhood. Create a stand to attract people who want some fresh produce and pretty flowers.
