The main objective of this research project was design a Virtual Learning Object (VLO) to first grade teachers at Cafam school about three-dimensional and two-dimensional figures characteristics and properties using Geogebra. To reach that goal, 4 phases were developed based on investigation-action research method: theoretical foundation, previous knowledge inquiry, VLO planning and construction and, implementation and evaluation. Previous knowledge and evaluation collected data were analyzed through qualitative and quantitative methods. VLO design used the eXeLearning software which includes 5 interactive activities with Geogebra (some of them include video tutorials), an objects and basic geometric relations bank with dynamic examples made by Geogebra, some kids activities links and other geometries introductory videos. The data collection and VLO implementation were done virtually with the 6 rst grade teachers at Cafam school technology classroom during 2019. Among main results, it is highlighted the positive teachers perception to VLO and GeoGebra as an important software in math teaching, besides the generated knowledge through objects and geometric relations revision.
