Beginning Algebra details
Beginning Algebra is a developmental math course at two-year colleges. The course includes factoring, equations, and functions in order to prepare the student for success in college mathematics.
For most students, our middle school math courses provide a more complete preparation for algebra. Colleges use developmental math courses for students who have completed middle school and high school math but have not qualified for college algebra.
Thinkwell's Beginning Algebra has all the features your home school needs:
- More than 180 video lessons
- 104 available contact hours (What is this?)
The number of contact hours in a course reflects the amount of time a student will typically spend completing the assignments in each course (i.e. watching videos, doing exercises, taking exams, etc...). Many people think about contact hours as the "seat time" for a course. Thinkwell provides this information so you can ensure that the amount of instruction in a Thinkwell course meets the standards and requirements for your state or region.
- 37-week lesson plan with daily assignments (see lesson plan)
- 1000+ interactive exercises with immediate feedback allow you to track your progress
(See sample) - Algebra practice tests and final tests for all 10 chapters, as well as a midterm and a final
- Printable illustrated notes for each topic
- Interactive animations with audio
- Real-world application examples in both lectures and exercises
- Closed captioning for all video
- Glossary of more than 350 mathematical terms
- Engaging content to help students advance their mathematical knowledge:
