They will make connections between the patterns presented in each representation. Equations will be examined in both expanded and factored form.</p><p>(This particular guide of this unit does not have direct ties to the thematic topic of Cap and Trade, however look for creative ways to support the theme as you explore these concepts.)</p><p>Unit design status: □ Complete template pages – Stages 1, 2, and 3 (Review use)</p><p>□ Completed blueprint for each performance task □ Completed rubrics </p><p>□ Directions to students and teachers □ Materials and resources listed </p><p>□ Suggested accommodations □ Suggested Extensions</p><p>Status: □ initial draft (date ______) □ Revised draft (date ______)</p><p>□ Peer reviewed □ Content reviewed □ Field tested □ Validated □ Anchored</p><p>Notes: Milwood Magnet School Biotechnology Magnet Curriculum Math 8 Unit 3, Guide 1</p><p>6-Page Template, Page 2 Stage 1 – Identify Desired Results Established Goals: A.RP.08.01 Identify and represent linear functions, quadratic functions, and other simple functions including inversely proportional relationships (y = k/x); cubics (y = ax3); roots (y = √ x ); and exponentials (y = ax , a > 0); using tables, graphs, and equations.* A.PA.08.02 For basic functions, e.g., simple quadratics, direct and indirect variation, and population growth, describe how changes in one variable affect the others. A.RP.08.04 Use the vertical line test to determine if a graph represents a function in one variable. A.RP.08.05 Relate quadratic functions in factored form and vertex form to their graphs, and vice versa; in particular, note that solutions of a quadratic equation are the x-intercepts of the corresponding quadratic function. A.RP.08.06 Graph factorable quadratic functions, finding where the graph intersects the x-axis and the coordinates of the vertex; use words “parabola” and “roots”; include functions in vertex form and those with leading coefficient –1, e.g., y = x2 – 36, y = (x – 2)2 – 9; y = – x2; y = – (x – 3)2.
