It's an old-fashioned idea, and maybe a little cliched, but running a lemonade stand has been a right of passage for kiddos for generations.
A lemonade stand does more than keep children busy. Running a microbusiness can be fun and educational, and it can teach an even greater lesson when your child commits to donate their profits to a charity, like Alex's Lemonade Stand Foundation to fight childhood cancer.
While this new venture might keep most kids busy for a day or two (or if they are like little me, maybe a couple of hours), it's a great way to pass the summer. Keep an eye out for garage sales, parades, festivals and other activities your little one could piggy-back on when setting up their stand in order to gain maximum profits (or donations). With any luck, your child will have a super fun time, work on their math skill and learn a little about economics — all under your supervision, of course :)
