Deriving the Quadratic Formula is usually the very first proof students have ever seen. To most students the proof looks like hieroglyphics. And to make matters worse, there are usually a few questions about it on the state test.
Here are the resources you need to get your students familiar with the proof for the Quadratic Formula as painlessly as possible.
A one-page guided notes student page on the steps to derive the quadratic formula.
A set of cards showing the proof in eleven steps (suitable for creating a card sort).
A page with the cards out of order so students can cut them apart themselves - to save you time.
A page for gluing the sorting cards in order.
A page for writing the steps to go with the steps as a response page.
A 3-item mini-quiz to prepare for possible questions on the state-test.
Common Core: Have students create a mini-poster on construction paper using the cut apart steps and writing response boxes. Have them try to explain the steps in their own words and then compare their words to yours.
***The student note page is from my complete unit of guided notes on graphing and solving quadratics which you can find in my TpT store.***
