Resumo
This paper proposes a sequence of activities to introduce the topic of compound interest in high school classes, also focusing on financial education. The aim is to show how the exponential impact of compound interest can, in the long term, boost the growth of investments or debts influencing the construction of an individual’s financial wealth. Some activities also give a first idea of the basic aspects of the Brazilian National Social Security (INSS), evaluating the positive and negative points, assisting in decision-making and possibly in the construction of investments that form a complementary retirement plan. When developing the activities, we try to work with the concepts of simple interest and compound interest in a contextualized way, using simple and accessible language. To support the preparation of this dissertation, we have analyzed the PROFMAT dissertation database in search of papers that contained in their titles the terms "Financial Mathematics," "Investments," and "Didactic Sequence" to verify which of them had more similarity with the objective of this dissertation. Also, we observed the strengths and main strategies used in the proposed activities thus enabling the elaboration of exercises that have a more efficient reach and lead to the building of skills in students that promote confident decision-making for a healthier financial life. As a main result, we expect that the didactic sequence proposed here will help students to realize that, in the long term, the dividends generated by financial applications outweigh the monthly contributions and represent the largest part of the individual’s wealth, thus evidencing the exponential effect of compound interest, which is also known as the "snowball effect".
