Mathematically Correct

Mathematically Correct was a U.S.-based website created by educators, parents, mathematicians, and scientists who were concerned about the direction of reform mathematics curricula based on NCTM standards.[1][2] Created in 1997, it was a frequently cited website in the so-called Math wars, and was actively updated until 2003.


Although Mathematically Correct had a national scope, much of its focus was on advocating against mathematics curricula prevalent in California in the mid-1990s. When California reversed course and adopted more traditional mathematics texts (2001 - 2002), Mathematically Correct changed its focus to reviewing the new text books. Convinced that the choices were adequate, the website went largely dormant.

Mathematically Correct maintained a large section of critical articles and reviews for a number of math programs. Most of the program opposed by Mathematically Correct had been developed from research projects funded by the National Science Foundation. Most of these programs also claimed to have been based on the 1989 Curriculum and Evaluation Standards for School Mathematics published by the National Council of Teachers of Mathematics.

Mathematically Correct's main point of contention was that, in reform textbooks, traditional methods and concepts have been omitted or replaced by new terminology and procedures. As a result, in the case of the high-school program Core-Plus Mathematics Project, for example, some reports suggest that students may be unprepared for college level courses upon completion of the program. Other programs given poor ratings include programs aimed at elementary school students, such as Dale Seymour Publications (TERC) Investigations in Numbers, Data, and Space and Everyday Learning Everyday Mathematics.

After Mathematically Correct's review of the programs, many have undergone revisions and are now with different publishers. Other programs, such as Mathland have been terminated.
