    La huerta escolar y la medida de longitud en la comprensión y solución de problemas matemáticos
    (Bogotá : Universidad Externado de Colombia, 2019., 2019-01) Cerón Molina, Jesús Antonio; Feria Uribe, Marco Antonio
    With the help of the educational cornmunity, the school garden was built as a didactic strategy, and from it, its impact on undestanding and solving problems related to the notion of length and perimeter measurement was described; since the students presented displayed difficulty when solving problems of this nature, as much in the internal tests as in the tests to know. For this, a didactic sequence was designed, in order to estimate, compare and measure the length of various elements of the school garden, therefore, it began, with the use of sorne body parts, as units of measure of length, for later, move to standardized units and with these bases establish the perimeter of beds and crop pyramids. The orchard was constituted in a context of learning, in which the students manipulated seeds, plants and instruments of length measurement and this unchained a management of technical vocabulary and an adequate mathematical communication; In this way, the comprehension and solution of problems was facilitated through the development of the three phases of the Mason method adapted to the fourth grade students.

    Uso del geoplano para contribuir a los conceptos de perímetro y área
    (Bogotá : Universidad Externado de Colombia, 2018., 2018-02) Ruiz Ariza, Sonia Patricia; Restrepo Santamaría, Ángela María
    The intervention proposal in the classroom consisted of determining the perimeter and area of flat figures without length measurements. The intervention allowed to consolidate the basic concepts of flat geometry and the development of metric thinking through the use of Geoplano as a concrete material. The pedagogical process was carried out with the organization and execution of a didactic sequence that started with the recognition of previous knowledge, from the diagnostic test and the continuous monitoring in the learning levels of the students, until the verification of results through the application of the post test. These results show the learning and characterization of the figures as well as the recognition of perimeter and area concepts in different plane figures.
