SOLARES PINEDA, Diana Violeta  e  BLOCK SEVILLA, David Francisco. Where is it better to cash the paycheck? Multiplicative knowledge developed by immigrant day laborers. Sinéctica [online]. 2017, n.49. ISSN 2007-7033.

This article examines the problematic relationship between scholastic and extracurricular mathematical knowledge in the context of rural education of migrant agricultural day laborer students. Didactic and sociocultural perspectives are used to address the issue. We present the mathematical knowledge of four underage agricultural day laborers tasked with solving multiplication problems that involve ratio comparison. The problems were designed based on a common daily situation for migrant day laborers, deductions incurred while cashing checks. The results show that even when families do not make numerical calculations-strictly speaking-to choose where to cash their checks, the interviewed children exhibited arithmetic skills that allowed them to make the necessary comparisons and choose the one in which the collection was lowest. This resourcefulness shows, on the one hand, a variety of non-conventional procedures, while on the other also demonstrates the absence of certain scholastic knowledge that could facilitate these calculations. We raise some reflections regarding the possible links between scholastic and extracurricular mathematics.
