Gifted mom - thank you I will look at that book and the Davidson article. You are very helpful. No need to appologize I think the school is not there yet with 80% Mastery.
When I talked to the teacher about challenging DS in more Math, she brought up he was pulling some 88% in 4th Grade Math. If you look at his work at that time, most missed anwsers are about the format/checking issues not understanding the Math. He also is so confident he just wants to zoom ahead. This checking issue and format issue is much improved. Right now he has a 95% in his 3rd Grade Math. I'm not sure about 4th Grade Math.
