3. The big idea of Unit 7 Incorporating SMPs into rational and radical expressions, equations, and functions Resources Welcome!

4. If we raise both sides of an equation to a power, we sometimes obtain an equation which has more solutions than the original one. Which of the following equations result in extraneous solutions when you raise both sides to the indicated power? Explain. Adapted from Illustrative Mathematics A-REI Radical Equations

7. What’s the big idea? Rewrite rational expressions Create equations that describe numbers or relationships Understand solving equations as a process of reasoning and explain the reasoning Represent and solve equations and inequalities graphically Interpret functions that arise in applications in terms of the context Analyze functions using different representations

8. What’s the big idea? Standards for Mathematical Practice

9. http://robertkaplinsky.com/ What’s the big idea? SMP 1 – Make sense of problems and persevere in solving them SMP 2 – Reason abstractly and quantitatively

10. Mathematical Understanding? http://robertkaplinsky.com/what-does-it-mean-to- understand-mathematics/

11. http://robertkaplinsky.com/what-does-it-mean-to- understand-mathematics/ Procedural skill and fluency Conceptual understanding The ability to apply mathematics Mathematical Understanding?

12. Coherence and Focus K-9 th  Rewrite expressions  Linear functions  Quadratic functions 11th-12th  Solve and graph functions  Model with functions.
