This study aims to present the experience lived through the development of a workshop by the
fellows of the Institutional Program Initiation Grant for Teaching - PIBID, the Degree in
Mathematics from the Federal University of Tocantins, Araguaína campus. The workshop was
aimed at students of the 8th grade of elementary school in the state School Center for
Comprehensive Support To Child Jorge Humberto Camargo, aiming a good understanding of
students in mathematics classes. Thus, the proposed workshop aimed to show a different approach
to traditional and the topic addressed was Notable products, and more specifically, the concepts
involved in the square of the sum of two terms, a product of the difference of two terms and product
sum by difference. Students had difficulty understanding the teacher's explanation of the subject
matter of algebraic form and face of these difficulties, the idea was to teach Notable Products
geometrically using the area calculations, without deviating from the teacher's explanation. The
workshop was easy to apply and the students themselves with the help of the teacher could build
the materials used. Another positive aspect of the workshop was that the students could work
together, helping each other and exchanging ideas and suggestions, and hence making the
mathematics class more interesting and profitable. The workshop was attended by several
challenges like riding a perfect square using only four figures, and they two squares of different
sizes and two equal rectangles, then calculate the area of each figure and add them up, finding the
same value obtained by algebraic form.
