abstract = {Summary: Researches on the nature and development of algebraic reasoning in early grades of primary education have been inconclusive about the boundaries between mathematical practices of algebraic nature and those not algebraic. In this report we define primary levels of algebraization in school mathematics activity and prototypical examples of answers to a task for each level, based on the type of objects and processes proposed by the onto-semiotic approach of mathematical knowledge. This model can be useful to develop the meaning of algebra in elementary school teachers and empower them to promote algebraic thinking in primary education.},
