K5 Learning has an online reading and math program for kindergarten to grade 5 students. I've been given a 6 week free trial to test and write a review of their program. If you are a blogger, you may want to check out their open invitation to write an online learning review of their program.
With one child in Kindergarten and another child in 4th grade I'm interested in trying out this educational website to see how it works for both of my kids. I'll check back in with my review after 6 weeks.
