I think my favorite after snooping around on their site would have to be MathLips.
Who wouldn't want to laugh with their child while they are learning how to solve math problems?!
KidCourses really has a way of making learning fun for your children.
Here is a bit of info about KidCourses.com: "Beginning in the 90s, kidCourses was NY-based and focused on running live courses in NY only. Our most popular course was the ABC Signs Program, a sign language program that was offered to Long Island preschoolers free of charge. When we tried to volunteer at a local library we were told “We don’t accept volunteers, we have to pay you” (generously). We then ran a mix of pro bono and paid courses. As a mom, it was great for Jessika to get paid for a gig where it was actually a plus to bring 2 little ones along. We were happy to offer live instruction to motivate children to be life long-learners, express their creativity, spread positivity, and just plain have fun. We had also established MathLibs® as a free online math resource. Now, with the kids all grown up and a westward move, we took a hiatus from delivering live courses (until now!) and started sharing our content online at (the new and improved) kidcourses.com."
Make sure you head over to their site, there is so much to check out!
