I was looking at a book called Mental Math. The author did his tricks infront of aidiences to amaze them. I'm not a Math/calculator head like my ds9 going into 3rd grade. Does any body think this stuff is good to introduce to kids this age? I think my son would love I but would it interfer would learning the math st school? Or cause some confusion. I wonder if anyone is familiar with this. My ds is gifted most strongly in math tested 9th grade on achievement test.He will do 5th grade Math at school nest year.
