We are starting 2.5 today. Use these videos that are linked to the page, as well as the 2.5 Reteach worksheet, to introduce yourselves to Algebraic Proofs and what they entail. The first video introduces lesson 2.5 and the second goes through two examples step-by-step so you know how to set up a proof and what they consist of. The 2.5 Reteach worksheet should get stapled into page 22 of your notebook.
Notice, that on your 2.5 Reteach worksheet the "symbols" and "examples" columns use conditional statements (if-then). We will go through more examples together as a class.
