When exploring options for virtual homeschooling, it is important for parents to accredited schools with the following SACS, MSCHE, NCA CASI NEASC, WASC WEB, and AdvancED. If you haven't included this in your google searches, don't panic. I have done an extensive search and will list the ones that I have found and list ones that came up popular but without accreditation.
First, Time4Learning.com is NOT accredited at all. It is only supplemental. Why is this important? If you enroll your child into the program and nothing else, it does not meet the minimum requirements for most U.S. state laws. Secondly, any online home school that is not accredited with the ones mentioned above may not be transferable to different numerous public and private education institutions including colleges. This is huge if you are planning on a college path for your homeschooled children. The cost of Time4Learning.com is roughly $20-$30 a month.
Second, International Connections Academy although accredited, their tuition is higher than some local private schools ranging from high 4k to 6k an academic year. If this price seems unreasonable, check your local private schools for cheaper tuition.
Third, K12 is free online public school. However, there are significant negative views in popular newspapers across the U.S. saying in numerous ways how it lacks. K12 is accredited but I would recommend you check reviews of your local K12 before enrolling. It is free so maybe worth looking into a little further.
Fourth, Mosaica Online is another AdvancED accredited school. It shows free tuition to several states including international students.
I would keep going, but I think you get the picture here.
Check out the website Guide to onlineschools to check regional accreditation. This could help you significantly cut down researching through a search engine and wasting time.
In addition, my child has an Auditory Processing Disorder (APD). When reviewing online supplemental curriculums such as Time4Learning vs Mathletics & Spellodrome, Time4Learning was way more interactive in K-2nd grade. My son needed total guidance and direction and the games seemed extremely unsupportive for children with learning disabilities by offering little to no sound or guidance through the website. With all this being said, I would still encourage parents with children without learning disabilities to use Mathletics and Spellodrome.
