Abstract: Paralelo à trajetória de Monteiro Lobato no processo de constitui o e consolida o das narrativas infantis enquanto escrituras dotadas de artisticidade, desenvolvem-se algumas concep es de leitura- pautadas em diversas teorias do texto e da linguagem – que fundamentam as práticas de ensino de literatura, formando leitores de acordo com determinado modelo. Este trabalho tem a inten o de apresentar as metodologias empregadas para contemplar as riquezas estética, ideológica, polissêmica e altamente sugestiva do ciclo O Sítio do Picapau Amarelo nas séries iniciais do ensino fundamental. Para tanto, s o recuperados os procedimentos pedagógicos a partir de um considerável levantamento bibliográfico. A seguir, será discutido a respeito das atua es do professor perante o texto plurissignificativo lobatiano, tendo como base as entrevistas efetuadas em seis unidades públicas de ensino de Presidente Prudente (SP).
