When my youngest grandson attended his first day of kindergarten he had a run in with his teacher. He started reading a math textbook and the teacher told him he couldn’t because he wouldn’t understand it. He said ....”No I already know multiplication and division and fractions.” Disbelieving him she quizzed him on his multiplication tables, which he aced. She asked him how much 1/3 plus 1/4 equals. He replied that 1/3 is 4/12 and 1/4 is 3/12 so they total 7/12. He then did three digit additions in his head. They promptly put him in a Gifted and Talented Program. He finished High School Algebra as a third grader. His great grandfather (my Dad) finished High School at 14 and entered Harvard Medical as a 19 year old.
