This work consists of an explanation of a rather valuable field of study that arises from an interface between language acquisition and variationist sociolinguistics - variation acquisition. From important studies conducted in this field, we approach concepts that are fundamental to the understanding of variation acquisition and children as members of the linguistic community. The aim of this work is to present a theoretical framework on variation acquisition studies, because this is a still poorly explored phenomenon in the Brazilian academic world. This work also presents a variationist research exercise, with child speech data on the verbal agreement variable phenomena (based on Scherre and Naro, 1998). For this purpose, we developed a data collection strategy, as proposed by variationist sociolinguistics, with some adaptations to children's work, as suggested by important studies, like those from Roberts (1997, 2002, 2005).
