This document summarizes a school project from CEIP SAN ANTONIO LA FOIA in Spain that uses puppets and the traditional tale "María La Castañera" to teach preschool children about the autumn season. The tale is about a granny named María who sells warm chestnuts in the mountains. The children do related activities like crafts, posters, and songs. They also make a poster collaboratively about autumn. As a final activity, a puppet of the chestnut seller comes to school and gives the children warm chestnuts to taste. The project uses a traditional tale and hands-on activities to teach children concepts about autumn in a fun way.
