Introduction At Yorba Buena High School, English Language Learners (ELL) students face barriers in connecting to textbooks and understanding academic content. Section 10.1 of the Algebra 1 textbook (Larson, Boswell, Kanold & Stiff, 2007) is analyzed for comprehensibility and strategies to support students to connect with the text on an intellectual level (Vacca, Vacca & Mraz, 2011) . Chapter ten of the textbook will be thought of in a tenth grade class during the week of March 11, 2012. Most of the students in this Algebra 1 class are classified as level three and four ELL students (Department of Education of California, 1999) and most students are fluent in conversational English. Included is a page from section 10.1 of the Algebra 1 textbook (Appendix A, Figure x), the page consists of approximately 250 words and defines five new content-specific low-frequency words. Textbook Analysis Section 10.1 of the Algebra 1 textbook analysis is performed in the context of a specific class, students, reading proficiency, and learning objectives. In essence the textbook is evaluated from the reader's perspective and learning of complex and abstract mathematical models. The goal of Chapter 10 is to develop the foundation for graphing and solving quadratic equations (Larson, Boswell, Kanold & Stiff, 2007). The applicable California Common Core content standards for mathematics are moderately vigorous and require students to:1. Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines. (Common standard A-SSE-3b)2. Create equations in two or more variables to represent relationships between quantities; Graphical equations on coordinate axes with labels and scales (limit to linear and quadratic).

Graphic organizers are one effective tool combined with sheltered instructional pedagogy to support ELL students in accessing grade-level content.
