<p>I homeschooled my daughter so was able to choose whatever sequences I wanted. I assume you have the flexibility at your school to select the order? Not all schools allow this …</p>
<p>The math question you raise is one that is raised quite often. I never saw any reason for splitting algebra in two and inserting geometry in the middle other than the historical one. It used to be that many schools only required one year of algebra and one year of geometry to graduate. And thus the traditional sequence was born.</p>
<p>For some, it helps to have all of algebra presented chronologically. They can then see how things fit together. They also don’t need the extended review of algebra 1 built into algebra 2 because less will be forgotten. Actually I think prealgebra and algebra can easily be covered in two years this way and this is what we did – but you obviously don’t have the same flexibility in a traditional school. The second year of algebra in the traditional sequence ends up being a recap of first year, some new material, and then something else worked in (a number of books have some trig, my son’s school worked in what they called “analysis” but I’ve never been clear on what that was).</p>
<p>You don’t mention your grade. If you took algebra 1 in 9th grade, I can see the reason for taking geometry in 10th – the PSAT in 11th. If you took algebra 1 earlier, this isn’t a concern.</p>
<p>As far as US History versus Euro, this wasn’t a choice we made because it made more sense to us to handle all world history chronologically over a number of years. Given a choice (unless the US History course is the easier at your school), I would say take Euro first. It then gives you a background and setting for what happened in the US – Europe being far more important and influential in the world until you get into the 20th century.</p>
<p>Finally, given the four science courses you list, if it were me, I would go biology, chemistry, AP Chemistry, and the AP Biology. Certainly it is useful to have had at least some chemistry prior to college-level biology. My son, at a private school, took two years of physics, then AP Biology, and finally AP Chemistry (no preliminary biology or chemistry courses – yes, this can be done). He found the AP Biology a bit difficult because it assumed a certain amount of knowledge of chemistry, which he had to pick up at the same time. (The teacher also only went through a fraction of the book, this being the first time she ever attempted the course. He had to self-study huge chunks of material prior to taking the test …)</p>
<p>Actually, a growing number of places have joined the “physics first” movement, believing that physics concepts underlie chemistry (which underlies biology). So, for instance, this is the sequence used in our local math/science magnet. The only real objection I’ve heard is that students lack the math to handle physics. But a year of algebra (and a few minutes learning some basic trig) is all that seems to be necessary. There are some people who don’t think you get real physics unless it is calculus-based, but this would mean most people couldn’t take it until college.</p>
<p>The sequence I used with my daughter was physics/astronomy, chemistry, physical geology, then biology, using college texts for each without difficulty (and science isn’t her thing either). I have another book that tries to present the basic concepts of all science in an integrated fashion. I notice that this is the sequence the authors found it useful to follow.</p>
<p>Just my opinion … through the years I’ve seen a number of discussions about math, history, and science sequences on homeschooling boards and agreement is NEVER reached :)</p>
