Class Experience

When I first transitioned from teaching science to teaching math, this course quickly became my favorite subject to teach. I love the elegance of geometry and logical reasoning and I particularly love teaching this subject using the inquiry method in the _Discovering Geometry_ text. I am so very excited to bring this course to Outschool!
Learners will need the following: 1. A copy of _Discovering Geometry_ (4th Ed) by Michael Serra. Please be sure you have the correct edition of this book (as opposed to the 3rd or 5th editions, which will likely also come up when you search for this title.) I choose the 4th edition because it offers an excellent curriculum but can still be found at an affordable price. This textbook can be purchased new for about $40 and used for as little as $6 ISBN-10 --> 1559538821 ISBN-13 --> 9781559538824 2. A geometric compass. In my experience, plastic compasses do not last as long and are more likely to loosen, bend, or break over time -- even a short period of time! I recommend a metal compass with an adjustment wheel in the center. Brands Blick and Staedtler make compasses like this for about $9. 3. A pad of tracing paper. 4. A durable ruler and protractor. (These can often be found bundled together with a compass as a "geometry kit" -- this can be a good value, but please be sure that the compass is the kind that I describe above so that you won't have to replace it later). 5. A college-ruled notebook, sharp pencils and a good eraser. 6. A scientific or graphing calculator. 7. All their notes from Quarters 1, 2, and 3. Aside from consumables, all the materials used in Quarter 1, 2 and 3 can continue to be used in Quarter 4.
Learners will not need to use any apps or websites beyond the standard Outschool tools.
1 hour 30 minutes per week in class, and an estimated 2 - 4 hours per week outside of class.
