Not sure about that. Our teachers are quite conservative (at my son's school) and it's hard to indoctrinate kids into "lefty" thinking with math.
"Common core" math? As for "lefty thinking".... it's a matter of "
this is how we say you're to now learn math (arithmetic, actually)"... not that math is Lefty itself.
Actually, the teachings of "common core math" are just a phony and convoluted way of doing arithmetic, aren't they? Can common core math be applied to anything bigger than adding up your restaurant bill, if even that?
If a kid is forced to learn "math" via common core, how does he apply that to any degree of higher mathematics? Or is "the Lefty prescribed way of doing arithmetic" the ultimate education objective in mathematics for today's kids?
IOW... how can you do algebra, trig, calculus and higher with "common core arithmetic" principles?
How does common core allow you to solve/understand.... F =ma?
Or even more simple..... "My yard is 100 feet long, 100 feet wide. How much lawn fertilizer do I need to buy to cover it?" Can today's kids figure that out? That kind of simple analysis is a valuable thing just to "get along" in life. Can today's kids do that with "common core" teachings?
