Reflection: Gradual Release Law of Sines - Section 4: Proving the Law of Sines for Acute Triangles


Teaching proofs is probably the most challenging aspect of being a geometry teacher. Should I spoon feed the proofs to students and just have them memorize or should I require them to come up with the proofs on their own? Is the main point to have them know the specific proofs or to master the type of reasoning and ingenuity it takes to write proofs generally? These are things I think about.

Check out this video to see how these questions inform my approach to teaching proof-writing.
