Nociones matemáticas evidenciadas en la práctica cotidiana de un carpintero del sur de Chile.

Despite the cultural wealth that exists in Chile, there are few studies that relate the mathematical notions present in cultural activities typical of the areas, such as the making of furniture. Based on the universal activities proposed by Bishop (1999), we characterize the mathematical notions present in the work of a carpenter from the south of Chile when he makes a bedtype piece of furniture and in some explanations about the making of a ship. Based on an exploratory qualitative methodology with an ethnographic approach, we conclude that in the work of making and preparing this type of furniture it is possible to identify universal mathematical activities. Finally, we reflect on how these notions could be linked with the Chilean curriculum, and the importance of relating the mathematics present in activities typical of each area in the classroom.
