This action research study examined the relationship between social–emotional learning (SEL) and early mathematical achievement among transitional kindergarten and kindergarten students in a large urban Title I elementary school. National organizations emphasize that high-quality mathematics instruction for young children must consider cognitive, linguistic, physical, and social–emotional development. Guided by this framework, the study investigated whether systematic SEL instruction using the district adopted Second Step curriculum would increase students’ SEL competencies and support growth in foundational math skills measured by the Eureka Math Module 4 assessment. Using a pre- and post-test design, data were collected from eight students who received structured SEL and mathematics instruction over one semester. Results indicated consistent improvement in students’ SEL competencies, including executive functioning skills, alongside significant gains in mathematical performance. These findings align with prior research suggesting that SEL supports school readiness, adaptive learning behaviors, and academic achievement.
