Algebra 1 is a complete high school algebra curriculum that is 100% aligned with the Texas Essential Knowledge and Skills (TEKS) and the English Language Proficiency Standards (ELPS). OpenStax Algebra 1 is a high-quality instructional material (HQIM) that is flexible enough for core adoption and adaptable enough to support a wide range of teaching strategies and student needs. Algebra 1 is a research-backed curriculum designed to strengthen teaching and learning in all classrooms. The OpenStax Algebra 1 curriculum is structured across nine units that guide students from linear to exponential to quadratic functions, emphasizing how these patterns differ. Students explore mathematical relationships through tables, equations, graphs, and real-world contexts, beginning with patterns of repeated addition or subtraction (linear), moving into multiplication or division (exponential), and culminating in models that both increase and decrease (quadratic). Each unit includes a readiness pre-assessment, multiple content sections, section assessments, and ends with a project, quizzes, and a wrap-up. The curriculum is designed to support coherent instruction, continuous assessment, and student engagement throughout the school year. Through our free, digital teacher guide (available within the “instructor resources” section of the website), teachers receive clear learning targets, prerequisite skill guidance, videos, and a breakdown of the Texas Essential Knowledge and Skills (TEKS) addressed in every lesson. Algebra 1 was authored by OpenStax and is based, in part, on the OpenStax Pre Algebra, Elementary Algebra, Intermediate Algebra, and College Algebra materials, and the IM 6-12TM by Illustrative Mathematics®. Based on OpenStax’s open (CC-BY-NC-SA) license, educators may remix and reuse the elements and content in Algebra 1 according to their approach and learning objectives.

Guía de Aprendizaje Matemático para Adultos con Escolaridad Inconclusa
Jessica Grandes-Padilla; Paola Duque-Sánchez; Hugo Barrionuevo-Montalvo; Miguel Casa-Chicaiza · Editorial Grupo AEA · 2024
El aprendizaje matemático para adultos con escolaridad inconclusa es un tema crucial para mejorar la calidad de vida y las oportunidades laborales de muchas personas. Estas personas pueden enfrentar desafíos únicos debido a lagunas en su educación formal, pero aún así, es posible desarrollar habilidades matemáticas sólidas. Un enfoque efectivo para enseñar matemáticas a adultos con escolaridad inconclusa es utilizar métodos prácticos y contextualizados. Esto significa vincular los conceptos matemáticos con situaciones de la vida real que los adultos puedan encontrar en su trabajo, hogar o comunidad. Por ejemplo, enseñar habilidades financieras básicas como el presupuesto, el manejo de dinero y el cálculo de intereses puede ser extremadamente útil y motivador. Además, es importante crear un ambiente de aprendizaje seguro y de apoyo que fomente la confianza y la participación activa. Los adultos pueden sentir vergüenza o ansiedad debido a sus experiencias previas de aprendizaje, por lo que es crucial proporcionarles retroalimentación constructiva y celebrar sus logros, por pequeños que sean. La tecnología también puede desempeñar un papel importante en el aprendizaje matemático para adultos con escolaridad inconclusa. Las aplicaciones y programas educativos pueden ofrecer lecciones interactivas, ejercicios prácticos y seguimiento del progreso, todo lo cual puede ayudar a los adultos a mejorar sus habilidades matemáticas de manera autodidacta y a su propio ritmo. El aprendizaje matemático para adultos con escolaridad inconclusa es un proceso desafiante pero fundamental para mejorar su calidad de vida y oportunidades futuras. Al adoptar un enfoque práctico, contextualizado y de apoyo, es posible ayudar a estos adultos a adquirir las habilidades matemáticas necesarias para tener éxito en la vida cotidiana y en el lugar de trabajo.
