Drawing from a qualitative approach and through individual pláticas (processes of co-constructing knowledge through dialogue) as a linguistic and cultural framework, this work explored informal contextual factors valued by Spanish-speaking Latina mothers of children, three to five years of age and enrolled in a nonprofit California preschool. Results revealed that Latina mothers have cultural forms of knowledge which impact their children’s educational experiences and engage in direct and indirect numeracy environments. While personal math experiences and home practices differed, Latina mothers experience and navigate their children’s learning based on sociocultural aspects, influencing how they support their children’s math learning. This study drew from sociocultural learning theories that value learning embedded within meaningful learning experiences. Patterns of family learning have several implications for educational practice, especially for Latine families whose parent participation is typically not as visible as White American English-speaking parents.
