Ampliando los conocimientos matemáticos en Educación Infantil: la incorporación de la probabilidad Ángel Alsina María Salgado Educación Probabilidad Educación Infantil lenguaje probabilístico indicadores competenciales actividad matemática competencial En los últimos años se ha incorporado la enseñanza de la probabilidad en el currículo de matemáticas a partir de los 3 años. Desde esta perspectiva, se presenta una propuesta para trabajar la probabilidad en Educación Infantil a través de una actividad matemática competencial, cuyo rasgo más característico es que se trabajan los primeros contenidos de probabilidad a través de los procesos matemáticos de resolución de problemas, razonamiento y prueba, comunicación, conexiones y representación. En concreto, se describe y analiza la experiencia “Probabilidad con cacahuetes” realizada con 22 niños de 5 años de un colegio público de la provincia de A Coruña (España). El grado de riqueza competencial de la experiencia se analiza a partir de 10 indicadores competenciales sobre el planteamiento y la gestión de las actividades matemáticas competenciales. 2019 artículo científico 0717-6945 https://www.redalyc.org/articulo.oa?id=243158860013 https://www.redalyc.org/journal/2431/243158860013/ https://www.redalyc.org/journal/2431/243158860013/html/ https://www.redalyc.org/journal/2431/243158860013/243158860013.epub https://www.redalyc.org/journal/2431/243158860013/movil https://doi.org/10.21703/rexe.20191836alsina6 es http://www.redalyc.org/revista.oa?id=2431 REXE.
