Textbooks, which serve as the backbone of the curriculum inmost mathematics classrooms, present a potentially powerful tool to help mitigate unequal opportunity to learn across students. Using the Surveys of Enacted Curriculum framework, we investigate the content of commonly used eighth-grade math textbooks in California and the extent to which they align with the Common Core State Standards. We also explore the relationship between the variation in content coverage and alignment and student characteristics. We find poor alignment between the textbooks in our sample and the Common Core State Standards and low overall levels of cognitive demand, but only limited evidence of systematic differences in alignment or cognitive demand coverage associated with student characteristics at the school or district level.  \nKeywords: content analysis, curriculum, descriptive analysis, equity, mathematics education, regression analyses, textbooks  \nIn 2004, the Williams v. State of California lawsuit contended that California public schools serving low-income students and students of color disproportionately lacked basic educational necessities like textbooks and safe facilities. Underlying these arguments was the notion of pervasive differences in students’ opportunity to learn (OTL), the simple idea that students cannot learn material which they have not been given the opportunity to study (McDonnell, 1995) . The suit reached a settlement where over $1 billion would be directed toward guaranteeing that all California students have high-quality facilities, textbooks, and teachers. Although more than 15 years have passed since Williams, inequities persist, resulting in unequal opportunities for students to learn.  \nA growing body of research indicates that textbooks may be particularly powerful tools in the effort to equalize OTL. The vast majority of teachers use textbooks in  \nmost of their lessons, making them the backbone of the curriculum (Polikoff, 2018) and ubiquitous in a typical student’s schooling experience (Blazar et al. , 2020) . Research suggests that textbook choice may be important for student achievement, with several studies indicating that the choice of textbook can affect standardized test scores in mathematics (Agodini et al. , 2010; Bhatt et al. , 2013; Bhatt & Koedel, 2012; Koedel et al. , 2017), though a recent large study found no such effects (see Blazar et al. , 2020) . In the context of the highly decentralized textbook market in the United States, where states, districts, schools, and even individual teachers may be involved in choosing from among dozens of possible materials (Polikoff, 2021), textbook choice may thus present policy makers with a potentially powerful tool to help equalize learning opportunities and improve education outcomes for disadvantaged students.  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative Commons  \nAttribution-NonCommercial 4.0 License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)) which permits non-commercial use,  \nreproduction and distribution of the work without further ","cbCaivxSqulUzppl","https://ap.wps.com/l/cbCaivxSqulUzppl","pdf",582645,18,"English","# Introduction\n## Williams v.
