Commercial and financial mathematics in the Lutheran parochial schools of Rio Grande do Sul in the first half of the 20th century

Abstract

The article discusses how commercial and financial mathematics was taught in the Lutheran parochial schools of Rio Grande do Sul, during the first half of the 20th century, through the analysis of the Segunda Aritmética and of the Terceira Aritmética of the Concórdia series, edited by the Lutheran Church for their schools. The methodological support is grounded on cultural history and on content analysis. The Missouri Synod, currently the Evangelical Lutheran Church of Brazil, began its mission in the German colonies of Rio Grande do Sul in 1900, by founding religious congregations and parochial schools.
