Mathematics education researchers agree that students' mathematical learning can be positively impacted by making connections to their out of school experiences through a funds of knowledge lens. This is especially important for diverse students whose experiences are often underrepresented in school curricula. Making these connections can be challenging for teachers whose experiences often differ from their students. We examine how conversations between preservice teachers and Latina mothers influenced the teachers' creation of a mathematics lesson that connected to students' out of school experiences. Findings suggest the importance of offering preservice teachers opportunities to learn from parents about their children's out of school experiences.
