The article reveals how the processes of subjectification and objectification proceed in a mathematical activity at a Japanese preschool and how the roles of finger gestures change for children during these processes. The theoretical construct used was joint labor as proposed by Luis Radford throughout his work. We relied in part on his methodology and in part on a microgenetic approach to analyze a scene of addition involving children and a teacher in a Japanese preschool. The analysis captured children obtaining help from the teacher to reconstruct the meaning of fingers as tools for solving quizzes rather than preserving the meaning through unprompted practice. The analysis also showed that the role of finger gestures was reconstructed in class to solve a conflict between children’s differing solutions to an addition problem.
