How to Find Easy Ways for a 13

Ask friends of the family if they need babysitting services. If a 13-year-old is mature, she might be able to babysit younger children. Even if she cannot babysit by herself, she can earn money by supervising children while there are other adults around. She can play with the young children, read them books, help them with homework or put them to bed while their parents are entertaining or are busy with other tasks.
Open a lemonade stand. This is a classic way for kids to make money, but it still holds. If selling lemonade seems too old-fashioned or babyish to your teen, try variations, like selling canned sodas or fruit juices or homemade baked goods.
Ask friends and neighbors if they have chores your child can do, such as weeding, mowing lawns, painting, house-cleaning or washing cars. Tech-savvy teens can help older folks set up and troubleshoot their computers, or do tech-related tasks like scanning old documents or photos into digital files. Pet lovers can walk dogs or be pet-sitters.
Look into tutoring opportunities. A 13-year-old could tutor younger children in basic skills. Contact elementary schools and tutoring centers to see what opportunities are available.
If your kid is a good artist or craftsperson, set up an account with a site like Etsy so that she can try to sell her creations.
