I was born in a small town in the department of El Progreso, Guatemala. In the bosom of a family of 5 members, my father, my mother, my older sister, my brother and me, the youngest. Since I was a little girl, I loved reading and math. When I finished elementary school, I received scholarships to attend high school and also to graduate as a teacher of elementary education (in Guatemala it is customary for students to choose a career in senior high school in order to be able to work), so I started teaching in private schools in my town at the age of 18. After several years of experience as a teacher, I entered the Centro Universitario de El Progreso of the Universidad de San Carlos de Guatemala to continue my university studies as a high school teacher with a major in Mathematics and Physics. I worked and studied at the same time and graduated in 2021, the same year I received a scholarship to travel to Japan and attend the Teacher Training Program in the field of Mathematics Education at the University of Tsukuba for one and a half years. Currently, I have been working for the Ministry of Education of Guatemala in a rural school since 2018, this school is multigrade, so I am a teacher and principal at the same time; this motivated the topic of my research project in Japan: Teaching Mathematics in a Multigrade School.
