A new book entitled Rethinking Mathematics aims to help teachers incorporate left-wing political ideology into their math lessons. In one example, the book suggests presenting math poblems that involve calculating how many of America’s founding fathers owned slaves.

And in another chapter:

Geometry teacher Andrew Brantlinger chronicles how he turned an ordinary lesson about calculating the area of a circle into an analysis of the South Central Los Angeles community that rioted after the 1992 “Rodney King” verdict.

During Brantlinger’s lesson, students learned that in 1992, South Central L.A. had no movie theaters or community centers, but it had 640 liquor stores. That led one student to conclude, “All they want them to do is drink.”

Apparently, in some quarters, teaching kids to add sums is less important than teaching them to multiply their racial grievances.
