The first version of **Common Core Geometry** is now done and completely posted. It consists of 10 total units:

The total text is now at 95 lessons with homework sets. I’m always happy if a curriculum is somewhere between 100 and 110 lessons. I’ve found over the span of my career that in a 185 day school year, the 100 lesson count is a good benchmark given all sorts of extra days needed for reinforcement, review, assessment, assemblies, fire drills, snow days/delays, Regents exams, and so many other things that stop us from teaching content.

I would assume as I now head into the Answer Key part of the process that I will likely add some additional lessons. There is no mention of surface area in the Common Core Standards or on the New York State Formula sheet, but I still think it is a topic worthy of inclusion in that last unit on Measurement. I’ve only included one lesson on radian measurement, but I believe that could probably use another day. I’m sure extra days on practice of proofs would also be helpful as well as reinforcement days here and there.

Of course, all of that may also come in our second version of the text. After the answer key is done, or partly done, we will begin work on the videos. We are planning on making these much better quality than those for Common Core Algebra I and Algebra II, so they may take some additional time to create. We anticipate beginning the videos in early February, but don’t have a completion date yet for those. We will have all materials ready for the 2017-2018 school year.

We invite teachers to use any of the Geometry lessons and homework sets we’ve posted. Because we have not begun the Answer Key, they are in their Beta version and teachers should work through them before giving them to students. We appreciate feedback both in terms of typos and in terms of mathematical content. I can promise we will correct the typos and will consider suggestions on mathematical content as long as they don’t radically alter the order or structure of the course.

Although Phase 1 of Common Core Geometry is now done, we have two phases yet to go (Answer Key and Videos). It’s about time I got started on Phase 2. I hope everyone had a great Thanksgiving and are ready to get the next month over with before the big break. As always, you can email me with feedback at: Kirk@emathinstruction.com.
