  • Math in the Modern World
    This assignment was created by Steven Cosares at La Guardia Community College. In it, “students are asked to gather nutrition data regarding their favorite snacks and assess how well they contribute to their maintenance of a ‘healthy’ diet, as defined through articles, websites, and guidelines established by the US Department of Agriculture.”
  • Precalculus [PDF]
    This textbook was created by by Thomas Tradler and Holly Carley at City Tech. It “has the overarching theme of ‘functions.’ This means that many of the often more algebraic topics studied in the previous courses are revisited under this new function theoretic point of view.”

The core concept of this course is helping teachers understand the needs of various Emergent Bilinguals (a.k.a. English language learners (ELLs)/English Learners (ELs), learn to use their language and culture as a resource in mathematics classrooms and implement research-based instructional strategies that are effective to teach mathematics for Emergent Bilinguals.”


  • forallX: an Introduction to Formal Logic
    By P.D. Magnus, professor and department chair in Philosophy at the University at Albany, this book “covers translation, formal semantics, and proof theory for both sentential logic and quantified logic.”
  • A Friendly Introduction to Mathematical Logic
    By Christopher Leary and Lars Kristiansen, this textbook introduces “readers with no previous study in the field […] to the basics of model theory, proof theory, and computability theory. The text is designed to be used either in an upper division undergraduate classroom, or for self study.”


  • College Algebra 2e (OpenStax)
    College Algebra 2e provides a comprehensive exploration of algebraic principles and meets scope and sequence requirements for a typical introductory algebra course. The modular approach and richness of content ensure that the book addresses the needs of a variety of courses.”
  • Linear Algebra with Applications
    “Overall, the aim of the text is to achieve a balance among computational skills, theory, and applications of linear algebra. It is a relatively advanced introduction to the ideas and techniques of linear algebra targeted for science and engineering students who need to understand not only how to use these methods but also gain insight into why they work.”


  • Data Analysis
    “This resource covers the following learning objectives: explain the uses and misuses of statistics; demonstrate an understanding of mean, median, mode, range, quartiles, percentiles, standard deviation, the normal curve, z scores, sampling error, and confidence intervals; graphically present data in the form of frequency tables, line graphs, bar graphs, and stem and leaf plots; design and conduct a statistics project; and analyze the data and communicate your observations about the data. This textbook was written for Adult Basic Education (ABE) Advanced Level Mathematics.”
