由于新冠在家上学，美国家长才知道自己孩子平常在学校干啥
It was invented so black people can do better in math.
While white people will sit down and memorize the addition andmultiplication tables, Black children won''t.
So the effort is to teach them how to reason out simple addition. E.G. 8 + 9take 2 from the nine and make it 78 + 7 + 2Now add the 8+2 to make 1010 + 7At this point, the child is supposed to be able to add 10 + 7It''s comical!
I watch my kid do this to her middle school math teacher onher Zoom meetings and he''s all "wtf are you doing?!"
