### 8th Grade Math Details

Thinkwell's 8th Grade Math course features online video lessons and interactive exercises that are both effective and enjoyable. It's the perfect fit for any homeschool curriculum.

Thinkwell's example-driven video lessons feature award-winning teacher Edward Burger, whose experience and passion make math easy for any homeschool student. In addition, 8th Grade Math includes thousands of automatically graded exercises that help your homeschool students put what they've learned into practice.

Thinkwell's 8th Grade Math has all the features your home school needs:

- Aligned to Grade 8 National Math Standards
- More than 100 topics with 250+ video lessons
- 36-week lesson plan with daily assignments (see lesson plan)
- 92 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.
