Know-How Exchange : Strategy

It sounds like you have some experience with one classroom using your materials to great success. The next step would seem to try this in multiple classrooms to ensure it works well and "test out" your material. So, one suggestion is to create a "first edition" of your materials and offer them for free to a local school district to use (in exchange for you watching how the kids use it, and with the ability to get footage of them using it for promotional materials). With your "first edition", also create a series of shorter videos and upload to social media sites (YouTube, etc.) to simply showcase your ideas. If you have the funds, hire some SEO experts to help you get more views and traffic to your website (you'll need one of these, too) and FB/Google+ pages. Finally, consider showcasing your program at national/regional/local elementary school conferences (such as the NCAEE, NAESP, etc.).
