The Forty Fifth Annual meeting of the North American chapter of the International Group for the Psychology of Mathematics Education was held PME-NA 45 in Reno, Nevada, October 1-4, 2023. The conference theme is "Engaging All Learners." Math learning should be a joyful experience for all students. When students are engaged and inspired, they are motivated to learn. Instruction that targets the learning needs and interests of our students makes it possible for students to excel in learning math. Participants in the conference explored how to create conditions to support learning that build on student engagement and interest in addition to other research engaged by the PME-NA community. The specific conference theme questions explored as part of the conference was: (1) How can we engage all students to learn math content by building on their interest and motivation to learn? (2) How do we design learning environments that take students and learning into account? (3) What are the design features of tools and curricula design features considering student engagement and interest in supporting learning? (4) How do we build partnerships with schools and the community to support student engagement and math learning? and (5) What research agendas should we pursue to ensure that all students reach their potential by paying attention to engagement and learning needs? The acceptance rate for Research Report was 45%, the acceptance rate for brief research reports was 70%. The acceptance rate for posters was 90%. Note: some papers were accepted in alternate format than originally proposed. The total number of participants who submitted proposals as co-authors was 1083. [Individual papers are indexed in ERIC.]
