My homeschooled 7 year old has similar MAP scores: Math 226, Reading 205, Language 212. We haven't done other testing. He is officially accelerated one year because he did kindergarten during the summer between leaving special ed preschool (he had language delays) and starting kindy at home. I don't plan on accelerating him officially any further, but rather just teaching at his level. Here's what we are doing with him next year.
Spelling Power: Rather than using their method, we are using the lists and inputting them into SpellQuizzer for practice.
Michael Clay Thompson: Grammar Island/Practice Island, Music of the Hemispheres (poetry), Building Language (vocabulary), Sentence Island (reading it only)
IEW: This will be our primary writing curriculum. Sentence Island, mentioned above, is supplemental because I like the way IEW has very specific and clear expectations.
Math: Math-U-See Epsilon, Zeta, and Prealgebra. He has completed all previous levels on an accelerated pace (he's a math kid). He's already teaching himself most of the Epsilon and Zeta level material so he'll just do the test book. I'll save the workbook for his sister to use. We'll also be supplementing MUS with Math Olympiad Contest Problems for Elementary and Middle Schools from AoPS because MUS is lacking in problem solving.
History: Story of the World with supplemental library books and some activities/crafts/projects/field trips to enrich
Science: Apologia Astronomy and Flying Creatures with supplemental library books and some activities/experiments/crafts/projects/field trips to enrich
Logic: Perplexors 4th-6th grade level. I'll get the regular chart style, venn diagram, and math books. We'll do these together as a team...DS, DD and I.
Foreign Language: He's requesting Korean so he and daddy will do Rosetta Stone as my husband has reason to learn Korean as well.
Literature: Various classic choices, usually related to history, science, or field trips (ie. reading a book that goes with an upcoming play). I'll use Teaching the Classics to help me know how to discuss the books better. I also allow my kids to read whatever they wish, trying to steer them to higher reading levels, when I can.
He'll also have cursive practice and I'm teaching both drawing techniques using the Draw Squad.
I don't know if this will help any but I know it helped me to see what curriculum others were using when I first realized my daughter needed more/different work.
