CK-12’s Math Concepts presents skill-based instruction. Chapters are organized in terms of key concepts and follow a logical sequence in which content builds across chapters. Each chapter is broken into short sections and includes an interactive outline with links to each section. Each section includes: (1) one or more embedded video tutorials that provide direct instruction in key content, (2) examples that provide step-by-step guidance in solving problems, and (3) sets of independent practice problems that closely mirror examples.
Video tutorials are presented as interactive whiteboard lessons with accompanying narration. Each chapter section includes problem sets that allow students to practice skills covered and each chapter concludes with a brief summary and a set of review problems. CK-12 does not include assessments, answer keys, or rubrics to support the evaluation of student work.
