## About Ask Dr. Callahan Geometry DVD Set w/ Printed Teacher Guide, Tests, Syllabus

Jacobs' math courses Elementary Algebra and Geometry: Seeing, Doing, Understanding are known for their clear explanations and strong, college-prep math. However, they've lacked the depth of teacher support (complete solutions manuals and teaching videos) available for other courses, making them less user-friendly for homeschoolers. The Ask Dr. Callahan series ends that! Each set of DVDs provides approximately 12 hours of lesson lectures that parallel the respective texts. Concepts are illustrated and problems (similar to those in the text) are worked on a white or black board behind the lecturer. There is an occasional use of illustrative videos which provides a break from the teaching environment. Solutions for assignment problems are not worked on the DVDs. The general feel of these DVDs is unscripted and casual rather than slickly professional. Dr. Dale Callahan is the instructor for the Geometry DVDs. The Algebra course is taught by Cassidy Callahan. In addition to the support offered to confused students by the DVDs themselves, there is more. Both courses are supported online via email answers (askdrcallahan.com) and the website also has a support page that answers common questions and is constantly expanding. One interesting aspect of the Geometry DVDs is the parallel that is drawn with logic arguments which occasionally include examples of biblical apologetics. Some basic equipment is required to complete the geometry constructions in that course. We'll be adding a set soon that includes this equipment: a compass, 6" ruler, 180 degree protractor, 45 degree triangle, 60 degree triangle, automatic pencil, eraser and spare leads.

Both DVD sets include a Teacher's Guide that includes a course syllabus, a test grading guide and grade sheets (either in printed, bound form or as pdf files that can be printed at home). The Geometry material provides an alternate testing option utilizing problems from the text, making the test book optional.~ Janice

### Category Description for Geometry: Seeing, Doing, Understanding My Father's World Printing

When Stephanie and Melissa finished Saxon Algebra 1 and started into Saxon Algebra 2 it didnt go well. Wisely, Linda decided to hold off on Algebra 2 and use Geometry by Harold Jacobs instead. After completing this course, they again started Saxon Algebra 2, follwed by Saxon Advanced Math, and did quite well. In fact, Stephanie scored a 30 on her ACT test in math, the highest math score that any of our children attained on the test. Why the turnaround? Was it just an extra year of maturity, or was it the way that Harold Jacobs presented the material that helped math to "gel" in their minds?

This latest edition of Jacobs Geometry preserves all the features that have made his text so popular with educators in the past. Like previous editions, this text stresses logic and deductive reasoning but does not take a "discovery" approach. This is an excellent geometry course with clear explanations of geometric concepts that include practice with proofs (informal and paragraph). The second chapter (six lessons) is appropriately devoted to logic in preparation for constructing proofs. Topics build incrementally and each practice set assumes knowledge gained in previous lessons in order to construct proofs. An appendix containing all presented theorems and postulates is most helpful. Also appreciated are the periodic algebra reviews, which keep students from forgetting these skills as they devote the year to geometry studies. This course is a thorough study of Euclidean geometry but concludes with a single chapter of four lessons that present non-Euclidean geometries. The teachers guide is solely an answer key providing answers to all exercises. The test book contains chapter tests, a mid-term, a final, and test answers.
