I was slow to follow the link to Why Do Americans Stink at Math?, in the New York Times Magazine, and I did not see it as a "must read" until I realized it was written by the Chalkbeat's Elizabeth Green.
I’m bad at math and I don’t see Americans’ problems with math as that big of a deal. I’m much more concerned with the challenge of improving reading comprehension in the 21st century.
As I understand it, math is a precise language, combined with logic. Few teachers are prepared to holistically teach this language or explain to students what the purpose and meaning of the subject is. Besides, contemporary American culture is not at its best in terms of valuing non-English languages, much less translating words and concepts into numbers and symbols.
Green grabbed me when citing John Allen Paulos’s diagnosis of innumeracy— “the mathematical equivalent of not being able to read.” She then reports that on the NAEP, “three-quarters of fourth graders could not translate a simple word problem about a girl who sold 15 cups of lemonade on Saturday and twice as many on Sunday into the expression ‘15 + (2×15).’”
