'''Common Core''' refers to an attempt by the [[federal]] government to impose its atheistic, leftist, and sub-standard education curriculum on elementary and high schools nationwide, in interference with the traditionally local control over education.  Sometimes "Common Core" is called "Common Core Standards."

As one of many examples of how "Common Core" dumbs down education, it its math curriculum fails even to reach the level of pre-calculus, and removes proofs from the teaching of geometry.

The mathematics part of Common Core pays particular attention to the use of proofs in the teaching of geometry, and the need for a uniform presentation of proof concepts between junior-high level and high-school level teaching.  See [http://www.curtiscenter.math.ucla.edu/downloads/Olson.pdf here] for an excruciatingly detailed analysis of some proofs about parallelograms and triangles in sections G.CO.10 and G.CO.11 of the Common Core.

 

Also, see [http://math.berkeley.edu/~wu/Progressions_Geometry.pdf here]:  "The geometry standards in the CCSS deviate from the usual geometry standards in at least two respects, one big and one small. The small one is that, for the first time, special attention is paid to the need of a proof for the area formula for rectangles when the side lengths are fractions."

Common Core deprives parents and local authorities of their control over education, and instead transfers control to unaccountable organizations and bureaucrats at the national level.
