Abstract

This work aims to explain the difficulties that eighth grade students face in solving the calculations of remarkable products, since some teachers are concerned with the applied teaching-learning process. This research presents a teaching proposal for teachers, using the elaboration and construction of concrete materials with paper clippings in the format of squares and rectangles for visualization of operations involving remarkable products. This work was carried out in an 8th grade class of a public school in the city of Itumbiara - GO. As a result of the pandemic, caused by the spread of the Corona virus, the research was readapted at the beginning and, even with a lot of difficulty to happen, the workshop was carried out in person and successfully at a favorable moment for the project at school. The practice performed with the paper clippings presenting geometrically the visualization of the calculations of remarkable products obtained satisfactory results for both the student and the teacher. This research proves through the final performance of the students, that the teaching proposal using concrete materials in the study of remarkable products effectively guarantees the construction of knowledge.
