Mar5-9

Standard 3: Geometry – The student uses geometric concepts and procedures in a variety of situations. Benchmark 3: Transformational Geometry – The student recognizes and applies transformations on geometric figures in a variety of situations. The student… 1. identifies, describes, and performs single and multiple transformations [reflection, rotation, translation, reduction (contraction/shrinking), enlargement (magnification/growing)] on a two-dimensional figure (2.4.K1a). 2. describes a reflection of a given two-dimensional figure that moves it from its initial placement (preimage) to its final placement (image) in the coordinate plane over the x- and y-axis (2.4.K1a,i). 3. draws (2.4.K1a): a. three-dimensional figures from a variety of perspectives (top, bottom, sides, corners); b. a scale drawing of a two-dimensional figure; c. a two-dimensional drawing of a three-dimensional figure. 4. determines where and how an object or a shape can be tessellated using single or multiple transformations (2.4.K1a). Application Indicators: 1. generalizes the impact of transformations on the area and perimeter of any two-dimensional geometric figure (2.4.A1a), e.g., enlarging by a factor of three triples the perimeter (circumference) and multiplies the area by a factor of nine. 2. describes and draws a two-dimensional figure after undergoing two specified transformations without using a concrete object. 3. investigates congruency, similarity, and symmetry of geometric figures using transformations (2.4.A1g). 4. uses a scale drawing to determine the actual dimensions and/or measurements of a two-dimensional figure represented in a scale drawing (2.4.A1h).
