This paper presents results of a practical and group activity of Integral Calculus, centered on intuitive concepts of speed and definite integral. The construction process was carried out with an experience of collecting speed data as a function of time during a pre-defined route using a smartphone application, “Waze”. The data were analyzed by students to approximate the value of the definite integral by adding areas in a graph of speed as a function of time to obtain the total distance covered. The result of the activity was very useful for the estimation of the value of a definite integral by the students.
