Atividades de explorações matemáticas utilizando matemágicas com baralho no ensino da álgebra e da aritmética

Abstract

The central idea of this dissertation was to try to overcome the difficulties presented by students in learning mathematics through mathematical exploration activities combined with teaching dynamics through mathematical magic, called Matemagics, with the aim of arousing greater interest, participation and enjoyment in the classroom, as well as contributing to the improvement of learning in mathematics by stimulating logical and mathematical reasoning and the ability to solve problems. The general objective of this of this research was to propose a didactic sequence through Matemagics using a common deck of cards, unveiling the mathematical trick in each of them to solve mathematical exploration activities with the students, highlighting the content covered in a comprehensive way, in a Cycle VI - EJA high school class with the aim of generating a better understanding and absorption of knowledge in the students. The matemagics with playing deck Worked in the research were Exposed to the students as well as the tricks behind each one were explained, highlighting and detailing the predominant mathematical content and skills in each matemagic. Contents involving basic algebra and arithmetic were used to explain and unravel each trick. The methodology developed in the activities proposed to the students was qualitative character and was developed by solving problem-situations and simple mathematical demonstrations that helped the students to obtain the results expected in the research. This research was carried out between October and December 2023, at the Dom Adauto State Comprehensive Citizen School for Primary and Secondary Education, located in the municipality of Serra Redonda-PB. The results of the research showed the effectiveness of improving students understanding of the content covered, with emphasis on teaching through mathematical explorations and Matemagic.
