Convergence: Where Mathematics, History, and Teaching Meet, is the MAA's refereed free online journal about the history of mathematics and its use in teaching. Aimed at teachers of mathematics at both the secondary and collegiate levels, Convergence includes topics from grades 8–16 mathematics, with special emphasis on topics from grades 8–14: algebra, combinatorics, synthetic and analytic geometry, trigonometry, probability and statistics, elementary functions, calculus, differential equations, and linear algebra. Explore its publications through Convergence’s Classroom Resources Index, indexes of stand-alone articles and of article series, and annual Tables of Contents.

Convergence resources for using the history of mathematics in the teaching of mathematics range from classroom activities and lesson plans to informative articles about the history of mathematics to teaching tools such as Mathematical Treasures, a collection of digital images of mathematical objects and texts from many museums and libraries.

We also have collections of portraits and snapshots of mathematicians that you may use in your classroom without special permission.

Besides historical images, articles about the history of mathematical topics from grades 8–16, translations of original sources, and classroom activities, projects, and modules, Convergence offers the following resources:

  • Historical problems.
    View problems from throughout the history of mathematics organized chronologically, geographically, or by subject.  Or browse the whole collection of Problems from Another Time, at left, which also includes articles with problem sets for students.
  • "On This Day" is a listing of three or four historic mathematical events that happened on each date.
    (See today's listings at the Convergence Home Page or pick any day you like at On This Day.)
  • Quotations. 
    (See "Today's Quotation" at the Convergence Home Page or browse the searchable database of quotations.)
  • The Calendar is an up-to-date guide to conferences and exhibits around the world that feature or include the history of mathematics and its use in teaching. It can be accessed from the Convergence Home Page.
  • Reviews of books, websites, and other teaching aids that focus on utility in the classroom.
    (See Critics Corner, at left, or the index of reviews to browse the whole collection of reviews that were published between 2004 and 2016. You may also search for reviews by author, title, or keyword, or browse the reviews listed in our annual Tables of Contents.)

Janet Beery served as editor from 2009 to 2019. Amy Ackerberg-Hastings and Janet Heine Barnett served 2019–2023 terms as co-editors of Convergence. Amy is serving a second term with co-editor Daniel E. Otero (2024–2028).
