Solving multiplicative structure problems with fractions in Primary School: Prior strategies to a teaching experiment
Résumé
In this paper, we present the study in progress that is being carried out to examine characteristics of the transition from natural to rational numbers when Primary School students solve multiplicative structure problems. A teaching experiment has been designed, including a pre-test, an instruction, and a post-test. In these pages, we focus on the first two phases of this teaching experiment and the beginning of phase three with a preliminary analysis of the pre-test. Results show the levels of success and strategies that students use when they solve multiplicative structure problems before participating in the instruction.
