Today we revisited a challenging proof, in which students had to prove that the sum of an irrational number plus a rational number is an irrational number. (This is from Lesson 2.2.) The thing that made this proof the most challenging is that it is virtually the first proof students have ever seen. They will eventually transition into a mindset that is used to thinking logically and creatively, using prior definitions and knowledge, in order to prove various conjectures.
Tonight's homework is p.90 (1-4).
