The annual publication of the Association of Teachers of Mathematics in the Middle States and Maryland became a quarterly journal called the Mathematics Teacher in 1908. W. H. Metzler, a professor at Syracuse University, served as its editor from its inception until it became the official journal of the newly formed National Council of Teachers of Mathematics in January 1921, with J. R. Clark as the new editor. In 1921, the present monthly schedule of publication for the school year was adopted.
