I founded Math Delights in 2008 to share some of my favorite mathematics-based activities, games, magic tricks, puzzles, and problems for kindergartners through 6th graders (5 - 12 year olds). Here are links to get you started.
Friends, colleagues, and teachers pointed me to the material on this website. I hope you, too, will tell me about any other delightful material that you find.
