Experience The Math Translator Difference
The Math Translator offers comprehensive instructional video support for the OpenStax books ranging from Prealgebra to Precalculus. 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. If you're homeschooling, this service can be used as a complete math resource for your children. 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 video library provides 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. 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. The Math Translator provides the most comprehensive instructional resource available for the OpenStax math textbooks.
About the Video Library Comprehensive Instruction to Accompany each OpenStax Math Textbook
Each video library is composed of three elements: comprehensive video lectures, homework support videos, and written answer keys for each practice test in the book. The video library outlines give an overview of the content of each lecture as well as suggested homework exercises. The answer keys for the Chapter 1 Practice Tests have been posted here; for the rest of the answer keys, please login.
