In this work the Problem Solving methodology is used as a tool for the introduction of the concept of matrices in High School. An experiment was carried out in five classes of the 3rd year of the High School of traditional School of the city of Rio de Janeiro.The contet was presented in a contextualized way involving subjects of the student's daily life. In three classes the problems were introduced before the formal presentation of the contents, while in the other two classes the problem were exploreda fter the formal presentation of matrices. This work presents two aspects that need to behighlighted:in part of the classes, matrix teaching was developed to solve problems; in the other hand, in the remaining classes, theteaching of matrices was accomplished through problem solving. Qualitative results a represented and discussed.
