Abstract
A class proposition with units of measurement and time organizing devices. A sixth year class of a public school. Assurances shaken. Growing suspicions. Established in a variation risk. Invention in processuality. Along with the training of research teachers and teacher education, a math class produces meetings with Education and Mathematics Education. How do we established ourselves with and clash with the established? How, in getting away with it, we invent ways of living and different worlds? Children involved ino with an activity of preparing and producing calendars. Breathing, submerging, emerging, escaping through cracks, clawing previous walls. Fluxes composing a math class. Writing training. Inventing school. Producing Education.
