The objective of this work was to identify the level of development of algebraic thinking in mathematics undergraduate students when solving quantity-sharing problems. For that, the model developed by Almeida (2016) was used as a basis, which proposes four levels of development of algebraic thinking in relation to sharing problems, level 0, absence of algebraic thinking; level 1, incipient algebraic thinking; level 2, intermediate algebraic thinking; and level 3, consolidated algebraic thinking. The research subjects were 64 students from the 1st period of the Mathematics Licentiate Course at a public university in the State of Pernambuco. Data collection took place through a test consisting of six sharing problems, which are characterized by having a known quantity that is split into unknown and unequal quantities. We found that most of the participants, 73%, found themselves with consolidated algebraic thinking when faced with a problem of sharing. However, some students arrive at the degree course in mathematics with this way of thinking without being fully developed, since 5% of the subjects are at level 1, that is, it mobilizes three characteristics of algebraic thinking, 8% of those surveyed find it if at level 2, that is, it mobilizes 4 features of algebraic thinking. It was also possible to notice that 14% of the research subjects are at level 0, that is, they cannot establish the necessary relationships to respond to a sharing problem, a problem that is related to a polynomial equation of the 1st degree, a mathematical object studied in elementary school.
