Resumo(s)
The project ‘Numerical thinking and flexible calculation: critical issues’ aims to study
students’ conceptual knowledge associated with the understanding of the different
levels of learning numbers and operations. We follow the idea proposed by several
authors that flexibility refers to the ability to manipulate numbers as mathematical
objects which can be decomposed and recomposed in multiple ways using different
symbolisms for the same objet (Gravemeijer, 2004; Gray &Tall, 1994;). The project
plan is based on a qualitative and interpretative methodology (Denzin & Lincoln, 2005)
with a design research approach (Gravemeijer & Cobb, 2006). This article focus the
preparation of a teaching experience centered in the flexible learning of multiplication.
It describes the analysis of a clinical interview where Pedro (9 years) solves the task
'Prawn skewers'. It illustrates how we identify and describe Pedro’s conceptual
knowledge associated with the different levels of understanding of numbers and
multiplication/division and analyzes if and how this knowledge facilitates adaptive
thinking and flexible calculation.
