O uso do material concreto e situações problemas para estimular estratégias de resolução de equação do 2° Grau

Abstract

This article has its treme: Second Degree Equation: The Dificulty and stralegy for solving problems situation in the 9th year of elementary school, whose general objective is proposing methodologies for mathematic learning facility which involves the second degree resolution practice by means of diferente techniques in different situations, doing that way an historical search and specifically to develop different techniques for solving problem situations, making the teaching of mathematics more attractive through concrete materials manipulation. It helps to minimize the leaners difficulties, stimulating them to develop mathematical text interpretation skills and stimulate their ability tocreat strategies for solving and verifying the results. The mathodology was based on camp and bibliographical research with qualitative and quantitave charecter making the numerical representant and the results description, based on authors such as Antunes: (2012), Dante-2005, and D’Ambrosio (2007). We conclude that using concrete materials in solving equations can improve student performance. Keywords: Equations. Difficulty. Strategies. Solution.
