This is a complete lesson plan on solving quadratic equations using square roots. The beginning of the lesson reviews basic square root properties, and then the lesson introduces the idea of having two solutions (a positive and negative square root) and applies that idea to solving quadratic equations. As with all my lesson plans, the package includes guided notes (PDF and Word formats), practice problems (homework), a quiz, and then corresponding Smart Notebook file. Everything you need to teach the lesson is right here. Just show up and teach. Kellen O'Connor
