Math:
6th grade is the perfect year to jump into online classes. Our first was with Natural Math and my daughter loved it.
Prodigy Math – online for grades 1-8. This was recommended to me by a teacher in New York. Set up help can be found on this page.
Acellus – online option for $30 a month, all subjects. My 8 year old in particular likes this one. Several homeschool families we know use this option for much of their learning. The classes are hit or miss, but it’s a good option for covering core subjects if you’re traveling for a few months.
Life of Fred – the books are often prices best on this page of Educents. It helps if the kids know some of the story from the earlier books before diving into the Pre-Algebra books – Pre-Algebra with Biology, Physics, or Economics.
