Field activities have figured as an excellent strategy for the teaching of the natural sciences. By imagining that field activities can also contribute to mathematics teaching, the research question arises: “Can field activity be used to provide environments conducive to teaching mathematics?” In this article, it is presented a field activity in the teaching of mathematics with the subsidy of Information and Communication Technologies (ICT) as instruments used during its development. The activity aimed to verify if the field activity can help in the teaching of trigonometric ratios in the triangle rectangle when making measures of heights of difficult access. To achieve this objective, the investigation involved a class of sophomore students attending technical high school at the Federal Institute of Mato Grosso, Campus Confresa. The parameters of the activities were produced together with the students, who were divided into three groups, conducting the activities out of classroom time and being advised through ICT. This study showed that field activities can favor the teaching of mathematics that is usually done in the classroom because the students felt part of the process and motivated by taking learning beyond the classroom.
