Crossing boundaries into secondary mathematics concepts: The case of functions

Crossing boundaries into secondary mathematics concepts: The case of functions.This paper reports on the use of a particular function machine which was based on the context of the ‘faulty oven’ to develop conceptual understanding of the concept of function among 4th class children. While the concept of functions is traditionally associated with secondary level mathematics, this research shows that the identification of appropriate models and contexts supports primary level children in accessing complex mathematical ideas. This approach was researched, developed, and tested in classrooms as part of a Lesson Study project with pre-service elementary teachers and mathematics teacher educators.Ye
