Estadística y probabilidad en infantil y primaria: Diez materiales manipulativos esenciales para desarrollar el sentido estocástico.

Statistics and probability is the most recently incorporated content block in the mathematics curriculum for infant and primary school. Its presence is due to the need to develop stochastic sense from an early age, so that children mobilise the knowledge and tools necessary to critically interpret data and make decisions in situations of uncertainty. In order to help early childhood teachers meet this challenge, the first part of this article describes the important knowledge and big ideas of statistics and probability to develop stochastic sense; and, in the second part, a selection of ten essential manipulative materials is presented, based on criteria of content, pedagogical purposes and type of material. For each material, various activities are described by age: 3-6 years; 6-8 years; 8-10 years; 10-12 years ​
