choirfarm Posted December 23, 2011 Share Posted December 23, 2011 I went to the curriculum store in the nearby town ( well an hour away). I looked at and bought a used BJU Geometry text for 50 bucks. For that 50 dollars I got the student text, 2 teacher texts, test/ quiz book, test/quiz answer key. If for some reason, the hive thinks this is an awful choice, I will just sell it back and recoup my money. That seemed like a good price for all of that. Ok. What I like about BJU- The concepts seem to be in a logical progression. The text is simple and not nearly as confusing as the HEATH text is. It is much simpler. He hasnâ€™t seen it, but this seems MUCH easier to read on your own than the Heath. I still might teach the material first. A lot of this book will be review. That said, Iâ€™m sure it will show me where his holes are. The teacherâ€™s edition is very helpful. It has tips and common areas where students get confused. I will not need the videos. Very simple. Cons- One of the reasons I have avoided any BJU products like the plague is the sledgehammer presentation of Christianity. I am a strong Christian, but the Geometry and Scripture section in each chapter is really stretching it. Do we really need to prove that Geometry can be found in the Bible? My son is going to roll his eyes at the heavy-handedness. The main concern I have, which may not be a concern is how much lighter it is than Chalkdust. I learned (by studying the BJU book) that analytical geometry is the intersection of algebra and Geometry. The BJU book has one small section in each chapter. Thatâ€™s it. The Heath book is FILLED with tons of analytical Geometry in every chapter. In the BJU book it has and A section for practice that are easy (much like the check for understanding in the Heath book), B that are harder and then a few C that are meant to be challenging. The majority of the Heath book contains the C like problems. I guess my goals for my son are these: For us to survive Geometry without killing each other, for him to have a good grasp of the basics of Geometry, to do well on the Geometry section of standardized tests. Here is a comparison of one chapter of the Chalkdust Heath book with what is in BJU. I would love any comments from you mathy moms. 3.1 Parallel, Perpendicular, and Oblique lines Theorem: Transitivity of Parallel Lines Theorem: Property of Perpendicular lines Some of this is in BJU chapter 2 3.2 Solving systems of linear equations Finding an equation of a line ( slope intercept form)) â€“ sometimes given points and writing equations, sometimes given equations and writing points, determining whether lines are parallel and perpendicular from the equation or given points and having to write equation to determine that WOW. Difference in BJU is striking. On in the middle of chapter 4 it explains what slope is and then has 4 problems with points to find the slope and then 2 graphs to write the explanation.. Chapter 6 has an analytical section on finding the equation of the line passing through a point and having a slope and then 5 problems to practice. Another one in chapter 13 where it just talks about how to tell if a line is perpendicular to the line by using the slope. 3.3 Contrapositives Laws of Logic ( BJU has an entire chapter on Preparing for proofs. Chalkdust seems to piecemeal it. Conditional statements are in 2.4, contrapositives here, syles of proof in 3.4. BJU covers all of this in their chapter 5) 3.4 Styles of Proofs: paragraph, flow and two-column - Having to write each style BJU- chapter 5. BUT only 2 column proofs are used. No mention of flow and two column in the entire book. 3.5 Properties of Parallel Lines Angles formed by transversals: corresponding, alternate interior, alternate exterior, and consecutive interior as well as all the theorems that go with them. BJU 6.4 3.6 Proving Lines are Parallel Converse of above theorems, constructing parallel The proof information is in 6.4, but there is no construction. 3.7 Vectors Writing a vector as an ordered pair, sum of vectors, dot product of vectors One sentence explaining what they are and how some people confuse them with rays and that they wonâ€™t be covered in this course.
