Ok, I'm in desperate need of some advice. The last 3 years I have taught Geometry in this order:
2. Pts, lines and planes
3. Angles, parallel lines with transversals
While I am happy with the logic materials I have put together, the math blogosphere has shown me that I could do a much better job with it. I thought that by moving Logic to after Triangles (and before proofs) that I could have more geometric context for logic and utilize sentences that use geometry instead of the nonsense sentences I use now. Yesterday I rearranged my first month of lessons and was thinking to myself, "self, you're doing a good thing!" However, one of my colleagues pointed out that in the Triangle unit, we teach the Pythagorean Theorem and its converse and that I need the kids to have logic first.
My question(s) to you is: In what order do you teach Geometry? Is it imperative that the students see logic and its vocabulary before seeing the Converse of the Pythagorean Theorem? (or will they survive just fine without that context?)
Thank you in advance for your feedback.
