Math History Tidbit:

Ethnomathematics: This term relates to the study of the mathematical experiences of those from different countries, from different ethnic and social backgrounds, or of a gender different from yours. Mathematics is a universal subject, but the ways different groups learn it, or experience it, very considerably. In 1985, the International Study Group on Ethnomathematics (ISGEm) was created. This group actively promotes programs to improve conditions for mathematics study by groups not usually encouraged to work with mathematics or mathematical ideas.
