f(n)=3n: Representaciones, estrategias y estructuras por alumnado de primero de primaria

Abstract

This work is part of a survey on functional thinking at an early age carried out in Spain (www.pensamientoalgebraico.es). We present part of the results obtained in a study carried out with first grade students (6-7 years). The general objective of this research is to describe the work of these students when solving a task that involves the function f(n)=3n. We focus on the representations, strategies, and structures they demonstrate. We highlight the formation of groups used by some students, the predominance of pictorial representation and the diversity of strategies in solving the task.
