This year I'm making one big change. I'm moving the constructions unit to the very end (unit 10). Constructions are so weird. There's too much to include it in my first unit (the Geometry basics unit is already long enough), but there really isn't quite enough to justify constructions being it's own unit. At the beginning of the year, constructions include angle bisectors, perpendicular bisectors, equilateral triangles, and shapes inscribed in circles. Throughout the year, constructions can be added. For example, transformations, points of concurrency in triangles, and tangent lines of circles. Throughout this past year, as I taught about inscribed and circumscribed circles, I had to re-teach angle and perpendicular bisectors. My hope is that by moving constructions to the end of the year, I will save time by not having to re-teach the basic constructions before teaching more complex constructions. Also, with moving constructions to the end of the year, I can plan what my students learn based on how much time we have. Since constructions are only a small part of the regents, if some things aren't taught because the priority was to spend more time on a more heavily represented topic, I can (sort of) live with that.
The small changes I made were re-wording some of my standards, and moving basic triangle topics to the first unit. Last year, I eliminated my triangle properties unit. Two topics that don't seem to be emphasized by common core are the Triangle Inequality Theorem and Midsegments of Triangles. I want to still teach these topics (especially Triangle Inequality Theorem), so I'm still incorporating them, but not spending too much time on them. This year I am also moving isosceles and equilateral triangles to the first unit. Last year, I taught isosceles and equilateral triangles during the triangle proofs unit, and it felt disjointed to me. My hope is that by moving isosceles and equilateral triangles to the beginning, we can just keep rolling through the proofs unit.
Here is my new unit breakdown:
1-Essentials of Geometry (All the introductory lines and angles and triangles stuff)
2-Transformations (Congruence transformations only)
5-Similarity (Dilations can be found here)
7-Measurement (All the fun 3D shape things)
- Since constructions is moved to the end, I'm excited to teach topics earlier in the year than normal. (Proofs in the first quarter and coordinate geometry before spring break for example.)
- I hope that teaching proofs earlier doesn't mean that my students shut down earlier.
- In light of the additional Cavalieri's Principle topic being included in the June 2017 regents exam, should I just plan to cover all of the additional common core geometry topics? Doing so does not align with my goal of focusing on the most important topics for longer periods of time.
