Specialized Knowledge, Fraction division, Teacher, resources, estimationAbstract
This study focuses on the knowledge revealed by mathematics teachers in a training course on fractions. Teachers solved a task regarding estimation, student difficulties and resources in the context of dividing fractions. The results suggest that teachers face some challenges such as: estimating the result of dividing fractions, listing students' possible conceptual difficulties, knowledge about resources and how to use them to teach dividing fractions. This research is relevant because students and teachers present difficulties in relation to the division of fractions, especially about the meaning of the fractional number, representation and reference unit.
