In Spring 2017, I taught a history of algebra course that culminated in writing scripts or films designed to introduce algebra concepts through history. With the students' permission, these are available for teachers and students of algebra to learn more about the context in which concepts were developed and evolved. Each script or film is accompanied by an introduction that discusses relevant common core algebra standards and a conclusion that provides a few sample problems connecting the historical material to practicing algebra today and suggestions for further reading. 

Scripts:

Algebraic symbols and Diophantus

The Babylonian algorithm

Coordinate geometry with Descartes

Finding maxima with Descartes and Fermat

Irrational numbers with Euclid and Hippasus

Probability with Pascal and Fermat

Quadratic equations through history

Films:
