Abstract
This paper explores teachers' responses when implementing a teaching approach that
encouraged children to develop and use invented algorithms for computation. The children
demonstrated number sense and used methods that predominantly reflected left-to-right
computational processes. While acknowledging the children's success and their ability to
explain and justify the methods used, the teachers faced a number of challenges. They
confronted previously held beliefs,perceived curriculum requirements and social expectations
regarding the place of standard algorithms for computation.
