Formulação e resolução de problemas com panfletos e propagandas: Uma proposta de ensino em Matemática Financeira como perspectiva para o letramento matemático

Abstract

The Formulation and Resolution of Mathematical Problems play a crucial role in both teaching and learning processes, as they help in the development of competencies and abilities, as well as in the consolidation of essential skills to promote Mathematical Literacy for students during Elementary school, as highlighted by Serrazina (2017), Loss (2016), Onuchich (1999) and Polya (1997), and also quoted in guiding documents (BRASIL, 2018, 2012, 1997). Thus, this paper investigated a teaching proposal based on the Formulation and Resolution of Problems, comprising Financial Mathematics, with a view on Mathematical Literacy for students in the ninth grade of Elementary school. We adopted the action-research methodology (ANDRÉ, 2012) and used a qualitative approach (GIL, 2008), to guide us through our methodological pathway. In order to obtain results, we applied a diagnostic questionnaire and a range of activities comprising Percentage, where the Formulation of Problems were promoted in 2 instances with the aid of advertisements, and we implemented a proposal for teaching financial mathematics using bank pamphlets which resulted in our Educational Product. The results obtained made us reflect and acknowledge the necessity to approach topics related to Financial Mathematics by using the Formulation and Resolution of Problems, as a strategy to develop Mathematical Competencies, Abilities and Skills and promote Mathematical Literacy at Elementary School completion.
