This article describes an investigation on the use of Scratch in the construction of the concept of angle, answering the question of research: What are the first notions of students in relation to the concept of angle in programming activities in Scratch? It presents a qualitative study, characterized as a multiple case study, carried out with 16 elementary school students from a public school in São Leopoldo.
