Myrnie of I Wonder Woman directed me to Head of the Class, a curriculum-based instruction with videos, multimedia, applications, and worksheets for free. I tried the Kindergarten level samples and liked it. The programs are described as supplements to education, so it won't be an all inclusive learning resource. Currently they offer content for preschool - fourth grade with grades five through eight coming soon. There are no downloads, but there is a required free sign-up for a password.
