Unit #: 2 Subject(s): Math II Grade(s): 9-12 Designer(s): Kristen Fye, Ashley Pethel, Kim Stilwill, Andrea Harkey STAGE 1 – DESIRED RESULTS Unit Title: Transformations Transfer Goal(s): Students will be able to independently use their learning to accurately describe and model transformations that occur in the real world. Enduring Understanding: Essential Questions: Students will understand that… Transformations (rotations, reflections, translations, dilations) can be described and performed through movements in the coordinate plane. Transformations can be represented in a variety of ways. Isometric movements can be achieved in a variety of transformations or a combination of transformations. Transformations have the ability to change an object’s size, but not its shape. Transformations have real world applications. Lines can be isometric through dilations if the line passes through the origin. Lines that are dilated that do not pass through the origin map to a line parallel to itself. There is a connection between changes in the constants and coefficients in a function and the graphical representation of that same function. Where can you apply transformations in the real world? What are the connections between transformations and spatial reasoning? How do points, lines, and angles influence transformations of 2dimensional figures? How do you describe isometry in terms of transformations? How do you represent and describe a transformation? How can you transform a line that is parallel to itself? What transformations can be represented by changes in the constants and coefficients of a parent function?

Identify the effect on the graph of replacing f(x) by f(x)+k, k f(x), f(kx) and f(x+k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them. Note: At this level, extend to quadratic functions and k f(x). Experiment with transformations in the plane. Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch). Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself. Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments. ACT Standards G.CO.5 G.CO.6 Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another. Understand congruence in terms of rigid motions. Use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure; given two figures, use the definition of congruence in terms of rigid motions to decide if they are congruent.

Find the point on a directed line segment between two given points that partitions the segment in a given ratio. Understand similarity in terms of similarity transformations Verify experimentally the properties of dilations given by a center and a scale factor: a. A dilation takes a line not passing through the center of the dilation to a parallel line and leaves a line passing through the center unchanged. Understand similarity in terms of similarity transformations Verify experimentally the properties of dilations given by a center and a scale factor: b. The dilation of a line segment is longer or shorter in the ratio given by the scale factor. Apply geometric concepts in modeling situations Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder). Apply geometric concepts in modeling situations Apply concepts of density based on area and volume in modeling situations (e.g., persons per square mile, BTUs per cubic foot).
