Connected Mathematics 3 Teachers Guide Grade 8 Butterflies Pinwheels And Wallpaper Symmetry And Transformations Copyright 2014 Connected Mathematics 3 Butterflies Pinwheels and Wallpaper Teachers Guide Grade 8 Copyright 2014 This Teachers Guide accompanies the Connected Mathematics 3 CMP3 unit Butterflies Pinwheels and Wallpaper designed for eighthgrade students This unit explores the fascinating world of symmetry and transformations building upon students prior knowledge of geometric shapes and their properties Unit Overview Butterflies Pinwheels and Wallpaper immerses students in the beauty and intricacies of symmetry and transformations through handson activities and engaging investigations Students explore different types of symmetry including line rotational and translational symmetry They learn to identify and describe these symmetries in various contexts including nature art and design The unit progresses through the following key concepts Symmetry Students learn to recognize and describe line symmetry rotational symmetry and translational symmetry in twodimensional shapes and patterns Transformations Students explore the concepts of translation reflection and rotation as ways to move and manipulate shapes They learn to perform these transformations on both geometric figures and patterns Tessellations Students investigate the creation of tessellations patterns that cover a plane without gaps or overlaps They learn to design and analyze tessellations connecting them to symmetry and transformations Symmetry in Real World Applications Students explore the use of symmetry and transformations in realworld contexts such as art architecture and design They learn to appreciate the role of these concepts in various fields 2 Unit Structure The Butterflies Pinwheels and Wallpaper unit is structured into five Investigations each focusing on a specific aspect of symmetry and transformations Investigation 1 Lines of Symmetry Students explore the concept of line symmetry and learn to identify lines of symmetry in various shapes They investigate the relationship between lines of symmetry and rotational symmetry Investigation 2 Rotational Symmetry Students delve into the concept of rotational symmetry identifying the center and order of rotation for various shapes They learn to classify shapes based on their rotational symmetry Investigation 3 Translations and Reflections Students explore the transformations of translation and reflection learning to perform and describe these movements They investigate the relationship between translations and reflections Investigation 4 Combining Transformations Students explore the concept of combining transformations understanding how performing multiple transformations affects the final position of a shape They investigate the creation of complex patterns using combinations of translations reflections and rotations Investigation 5 Tessellations Students learn about tessellations patterns that cover a plane without gaps or overlaps They investigate the relationship between tessellations and symmetry exploring how symmetry is crucial for creating tessellations Teaching the Unit The Teachers Guide provides a comprehensive framework for teaching the Butterflies Pinwheels and Wallpaper unit Each Investigation includes the following
