Personal experiences lived in the 9th grade of primary schools where we studied studied the second degree equation we were taught that to find the roots of an equation Bhaskara form is used to find the roots of an equation, but what we were and is still shown is something very superficial, usually without contextualization, the teacher teacher passes on what is taken from the books only with formulas and exercises. exercises. Through this work we tried to show the contextualization of problems, which students often only observe when they go to do tests required by the government and other institutions such as Brazil test, Enem, Olympics of Mathematics. The general objective of this work is to contribute to the improvement of teaching and learning of 2nd degree equation through contextualized problems in the 9th grade of primary schools. As specific objectives we highlight: select questions 2nd degree equations contextualized questions from textbooks that allow the use of concrete material concrete material; elaborate activities using concrete material to help in the interpretation and the interpretation and resolution of 2nd degree equations obtained from contextualized problems contextualized problems; apply the activities in 01 class of 9th grade grade and evaluate the results obtained after the application of the activities proposed in the research.
