ALGEBRA & TRIGONOMETRY COURSE
Get a Full Microlearning Course that is available entirely within your own learning environment (LMS) or ours.
The Algebra and Trigonometry course contains 91 selfgrading microlearning lessons that work instantly inside your Learning Management System (LMS).
Written and reviewed by a team of highly experienced instructors, Algebra and Trigonometry provides a comprehensive and multilayered exploration of algebraic principles. It is suitable for a typical introductory algebra course, and was developed to be used flexibly. While the breadth of topics may go beyond what an instructor would cover, the modular approach and the richness of content ensures that the course meets the needs of a variety of programs. Algebra and Trigonometry guides and supports students with differing levels of preparation and experience with mathematics. Ideas are presented as clearly as possible, and progress to more complex understandings with considerable reinforcement along the way. A wealth of examples—usually several per lesson—offer detailed, conceptual explanations, in order to build a strong, cumulative foundation in the material before asking them to apply what they’ve learned.
