During the dog days of summer, kids need something fun to do. The Lemonade Stand Start-Up Activity Kit from Bizainy can help inspire entrepreneurial spirits—and help kids score some extra cash, too. The kit includes essentials for hands-on business fun like banners, books, decorate-your-own money boxes, signs, sales pads, and even business cards. The activity kits encourage entrepreneurship among kids, along with creativity and fun. And since a lemonade stand is serious business, the kit comes with its own 20-page book with a marketing plan, budget, sales strategies and more! The only thing your kid will need to decide is if he’s going to serve traditional yellow or pink lemonade ($30, bizainy.com).
