The aim of this study was to analyze adult education students at different levels of education, solving activities of construction and interpretation of graphs. The results showed no significant differences in student performance in activities of interpretation depending on the level of schooling. In the construction of several graphics problems were observed. Most of the plotting did not provide the information necessary to understand it. Difficulty with the scale was one of the most evident among the students. We observed that the performance of students who have achieved success with the activities of interpretation failed to ensure proper construction of a chart. This suggests that there is little relationship between such activities and that graphs interpretation was easier than construction. The data suggest that there is a need to encourage the construction of charts and for teachers to integrate activities of interpretation with the construction of graphs.
