The purpose of this paper is to demonstrate the mathematical understanding of Latino immigrant parents in curricular and pedagogical practices in elementary school. The paper seeks to counter widely spread deficit discourses about the parental involvement of Latinos in education. Using data from the Agency and Young Children project, a video-cued ethnographic study (Tobin, Wu, & Davidson, 1989; Tobin, Hsueh, Karasawa, 2009; Tobin, Arzubiaga, & Adair, 2013), we highlight aspects from home that schools can use as resources to build a bridge that supports children's mathematical understanding.
