### Specialized Language of Mathematics

The *High School Publishers’ Criteria for the Common Core State Standards for Mathematics* says that materials aligned with CCSSM should emphasize mathematical reasoning by “explicitly attending to the specialized language of mathematics.”

I am greatly concerned by this, as there is much confusion about many of the most important words in mathematics.

Words like *dodecagon*…

…or *coordinate axes*…

…or *hypotenuse*…

…or *quartiles*…

…or *spheroid*…

The Common Core mathematics glossary contains 52 terms, yet none of the five listed above are on that list. I certainly hope the glossary committee will consider adding some of them.
