In the homeschool GT community kids doing "easier" curriculum certainly move faster than kids doing "harder" curriculum like they might use in Taiwan from what I've seen.
I am actually asking about a home schooled child who is working through 2 of the more advanced math programs (Singapore and Horizons) at least 3 years ahead of her chronological age compared to our local public school. Math and science are her strengths. They are NOT my strengths and I'm having a very hard time coping (if that's the correct word) with her ease and speed in math.
Thanks for everyone's helpful responses! What prompted this post was basically this: I thought she was about 2 years ahead of her age in math. Then recently I looked on the local school district's math curriculum map and discovered that she is THREE years ahead of what I thought - according to our local ps. I guess I didn't take into account how advanced Singapore and Horizons are. But it was just a little bit of a shocker. And she has been asking for harder math. Sorry, but my heads spins sometimes!
I thought maybe there was something that I couldn't find (on Hoagies, from Ruf or Webb) that kind of tells you if your kiddo is about x amount of years ahead, then they are gifted and if they are xx amount of years ahead then they are HG, and so on. I guess it's kind of a dumb thing to ask but I really do appreciate this discussion.
