This app provides access to ALL your Teaching Textbooks (TT) Pre-Algebra course materials on a Windows device! Enrollment in the TT Pre-Algebra course is required. The Teaching Textbooks Pre-Algebra app makes your TT course even better! Not only will your student enjoy math while learning independently, but, with the app, that learning can also take place on the go. Even when offline! Specifically, the app can be used offline for up to 6 lessons at a time. That makes it perfect for homeschool parents who need their kids to stay productive while the family is out and about during the day.
