U.S. society has persistent expectations of what it means to be a mother or a mathematician. However, the voices and experiences of mothers who do mathematics with their children is not factored into these expectations. The purpose of this study is to use a mother-centered perspective to investigate how mothers engage with their children in teaching mathematics at home. The study responds to the following research questions: How are mothers positively engaging with their children and mathematics? In what ways does their previous experience support or contradict this activity? How does current engagement and past experience of mothers reflect gendered and racialized perspectives of motherhood and mathematics? Using identity theory, this work critiques existing limited norms of motherhood and mathematics education by focusing on the constructed identities and spaces mothers use to support their children in learning mathematics. Narrative inquiry is used to understand the diverse experiences of the five participants through interviews, observations, and debrief sessions. The findings show the impact of experiences on the participants’ mathematical action at a personal and societal level. On a personal level, the participants’ past experience with mathematics in school, current feelings about mathematics and their children’s interests shape how they see themselves and inform the mathematical activity they engage in. On a societal level, participant stories show a common theme that recognizes institutional whiteness and gendered binaries embedded in the expectations of both motherhood and mathematics. The participants’ past experiences in school that shape mathematics as limited to whiteness and masculinity impacts how they see themselves as mathematically capable today and thus choose to interact with their children in mathematical learning.
