Summary: We carry out a biographical study of a 2nd year student of ESO who studies integers and algebraic expressions using the teaching material ``algebraic puzzle" as an analogical register. Their productions are analysed in a pre-test, a post-test, class tasks and interviews, with the purpose of knowing the personal meanings that she gives to integers and algebraic expressions. Also, a study of student's errors is made in order to investigate their origin.
