The Arithmetic-Algebra Connection:

A Historical-Pedagogical Perspective

K. Subramaniam and Rakhi Banerjee

Abstract The problem of designing a teaching learning approach to symbolic al-

gebra in the middle school that uses students’ knowledge of arithmetic as a starting

point has not been adequately addressed in the recent revisions of the mathematics

curriculum in India. India has a long historical tradition of mathematics with strong

achievements in arithmetic and algebra. We review an explicit discussion of the re-

lation between arithmetic and algebra in a historical text from the twelfth century,

emphasizing that algebra is more a matter of insight and understanding than of using

symbols. Algebra is seen as foundational to arithmetic rather than as a generalization

of arithmetic. We draw implications from these remarks and present a framework

that illuminates the arithmetic-algebra connection from a teaching-learning point of

view. Finally, we offer brief sketches of an instructional approach developed through

a design experiment with students of grade 6 that is informed by this framework, and

discuss some student responses.
