Dilations in the Coordinate Plane 8GA3💗

############################# Video Source: www.youtube.com/watch?v=E8lrJnuI0As

This video lesson introduces dilations. Dilations are a transformation that changes the size of a figure by enlarging it by a scale factor greater than one or by reducing it by a scale factor less than one. Real world examples are provided. Figures will be dilated about a center of dilation. Instruction is provided to learn to dilate in the coordinate plane with the origin as the center of dilation. Student practice is embedded with modeled exemplar problems. • #geometry • #dilations • #dilateusingascalefactor • #dilateabouttheorigin • FREE Edpuzzle - https://edpuzzle.com/media/636297b0e9... • Purchase an Editable Copy of the Google Slides used to Create this Video - https://www.teacherspayteachers.com/P... • Website: www.magicofmath1.com • Grade 8 Transformations Unit Playlist - • Transformations UNIT -Grade 8 Math fr... • 💗 Preparing for the Unit - Review The Coordinate Plane and Graphing • • Getting to the Point: Reviewing the C... • 💗Congruent Figures - How to Define and Identify • • HOW to Graph Points (on the Coordinat... • 💗Translations - The Mathematical Slide • • How to Perform Translations: The Mat... • 💗Reflections - The Mathematical Flip • • Reflections: Flipping over the x- an... • 💗Rotations - The Mathematical Turn • About the Origin - • How to Rotate Figures in the Coordina... • About a Vertex/Point • • Rotate a Figure about a Vertex in the... • 💗Similar Figure - How to Define, Identify Use • • Understanding Similar Figures | 8.G.A... • 💗Dilations - The Mathematical Change in Size • • Dilations in the Coordinate Plane | 8... • 00:00 Introduction • 00:29 Vocabulary • 01:56 Dilations in the Real World • 02:25 Enlargement - Dilation • 02:46 Reduction - Dilation • 03:08 Scale Factor - Enlargement • 04:31 Scale Factor - Reduction • 04:55 Dilated Figures and Images • 05:44 Dilations on the Coordinate Plane • 08:24 Student Practice #1 - Dilation • 09:57 Student Practice #2 - Dilation • CCSS.MATH.CONTENT.8.G.A.3 • Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. • CCSS.MATH.CONTENT.8.G.A.4 • Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.
