William McCallum, one of CCSSI’s authors, wrote in the comments section of an article appearing on The Atlantic Magazine website, written by Barry Garelick, ``I agree with you that there is a lot of misreading of the standards out there in the field, and this is a problem.’’ Such arrogance. The real problem is that CCSSI is poorly written, not only substantively, but also in its lack of clarity.
7.G.2’s ``Focus on constructing triangles from three measures of angles or sides...‘’ is at best, ambiguous. Writing intelligible English is not the same as constructing logic gates, where the definition of ``or’’ invariably includes the possibility of both. The parallelism in the sentence implies you are given either 3 angles or 3 sides, but we suspect it’s supposed to mean the following: ``Focus on constructing triangles given various combinations of three angles and/or sides.’’
