Using an online textbook such as one containing the concepts of Algebra 1 often begins with the purchase of a subscription to the online textbook itself, though some books are available for use free of charge. After accessing an Algebra 1 textbook, users can navigate through chapter titles and sub-sections containing the subject's core concepts.
Online textbooks typically require an access code to be used as educational resources. The websites sponsoring these textbooks usually offer the option to create an account from the perspective of a student or an educator, enhancing the way users can interact with a subject such as Algebra 1.
Many textbooks, once accessed, are viewable in easy reading formats and follow the same page numbers and layout as a physical textbook. Pearson offers an online Algebra 1 book that is navigated in this fashion, with a searchable table of contents and links to different sections and outside information about core concepts.
McDougal Litell's ClassZone feature is a companion to an online Algebra 1 textbook offered by the company, with intuitive links to each section and self-tests aimed at helping the user grasp concepts from simple variables to working with radicals and factoring equations.
Many online textbooks are paired with chapter tests, links to additional information and suggestions on ways to apply or practice concepts learned in the digital book.
