This work presents experiences of a pedagogical intervention conducted in 2nd-year high school classes of a public school in the state education network of Vitória - ES. Planned interventions were carried out within the scope of the Pedagogical Residency Program (PRP) of the Mathematics Teaching Degree course at the Federal Institute of Espírito Santo (Ifes), campus Vitória. It involved trigonometry concepts, through raising awareness of the importance of accessibility ramps, supported by critical mathematics education. Manipulative materials were used as didactic tools in Geogebra, along with a presentation during interventions in synchronous remote sessions. According to the achieved results, the critical approach is a significant alternative for the teaching and learning process. When working with the topic at hand, we planned a class that went beyond mathematical content, concluding that the activity contributed to everyone thinking critically about this topic, which is extremely important in our society.
