Depends on the kid and the parents but just for kicks look at:
Michael Clay Thompson (language arts book set, pricy & flighty)
Hands on equations (young kid's algebra manipulatives)
Calculus by and for kids (workbook)
Maria Miller- mammoth math (you tube + workbooks)
Aurora Lippor (monthly subscription-worked for NASA at 17, now does online science class for kids/ monthly subscription, pricy but real fun)
History's tough- Christian -story of the world. Non Christian usborn Internet linked world history encylopedia for overview. Supposedly history is three 4-year cycles- 1st to learn names& stories, 2nd to learn details, 3rd to analyze
Handwriting without tears (5th grade for non-babyish printing instruction)
Mothering.com has cirriculum forums, leans twords child-led
Well-trained mind forum has reviews, leans twords religious
Can help you more if you're more specific.
