Experience The Math Translator Difference
The Math Translator offers courses ranging from Prealgebra to Precalculus. It is designed to be a comprehensive instructional tool for any math student. If you're homeschooling, this service can be used as a complete program for your children. If you're a public school student, this website can be used to adjunct the classroom instruction you are receiving. If you're a teacher/professor, these videos can be used as a lecture source in your online or hybrid courses or as a supplement to your classroom instruction. In addition to the video instruction on this site, you will find answer keys for the practice tests in each chapter of each book.
About the Textbooks Experts in their Field
The Math Translator courses provide companion instruction to the OpenStax™ math textbooks. OpenStax is a nonprofit educational initiative based at Rice University. The authors of the OpenStax textbooks are content experts in their field. The textbooks are peer-reviewed, openly licensed, 100% free, and available online. The OpenStax's mission is to “improve educational access and learning for everyone”.
About the Videos Created by a Tenured Math Professor
My mission as The Math Translator is in direct alignment with the OpenStax mission and The Math Translator is an OpenStax Partner Ally. I believe strongly in the value and importance of education and I know that high-quality instruction is a crucial component of learning mathematics. My videos provide companion instruction to the OpenStax math textbooks. Every section of every book has a comprehensive 1-hour lecture video that teaches that section's learning objectives in depth. In addition to this, I have recorded video explanations for every other odd homework problem in each book. Comprehensive instruction is vital for learning mathematics, especially in an online environment. The Math Translator provides the most comprehensive instructional resource available for the OpenStax math textbooks.
About the Courses Comprehensive Instruction
The Math Translator courses take you back to the basics because learning math does not have to be complicated. Each course is composed of three elements: comprehensive video lectures, homework support videos, and written answer keys for each practice test in the book. The course outlines give an overview of the content of each lecture as well as suggested homework exercises. The course calendars give a suggested timeline to complete each course within a 9-month period. The answer keys for the Chapter 1 Practice Tests have been posted here; for the rest of the answer keys, please login.
