These answers, typical of the future teachers we classify into this profile, show that they use some important mathematical elements to describe the answers of primary school students, but instead of using these elements as the basis for inferring the characteristics of understanding of pattern generalization, they use generic language that refers to making or not making mistakes, the difficulties the students have or the language they use. They are able to identify some significant mathematical elements when they describe the primary students’ answers, but they do not use them to interpret the understanding of the students.
