Abstract | This article focuses on issues around flexibility in mental calculation. When calculating a subtraction or multiplication mentally, it is desirable for students to use a method that suits the problem-to be flexible-but is it fair to describe this as "strategic flexibility"? What exactly is it that happens when someone `decides' to tackle a mental calculation in a particular way? In the article, I make some distinctions among strategies and strategic flexibility in mental calculation to explore and try to clarify the terms and associated ideas. At the heart of the article is an argument that the model of strategic choice is not able to give an adequate account of strategic flexibility in all aspects of mental calculation, and an alternative is proposed. |
