Sequências numéricas no Ensino Médio

Abstract

This paper presents a didactic proposal for the content of numerical sequences, comprising the treatment of arithmetic and geometric progressions, content commonly taught in the rst year of regular high school. In this sense, chapters are developed with a historical ap- proach, curriculum and discussion of how the curriculum should be divided and discussed in meetings. The introduction of the theme sequences is made using the historical period and the puzzles of Hanoi Tower and Jumping Frog for, from the rediscovery process, lead students to recognize patterns and formulate conjectures. For arithmetic and geometric progressions chooses to emphasize problem solving situations and formalization, demons- tration, the results presented, it is believed that this may contribute to logical-deductive and argumentative development of students. Three evaluation activities are suggested with the objectives and possible resolutions of the issues proposed also exposed in the chapter discussing the meetings in which the curriculum was divided.
