Mathematics for the Elementary School, Unit 6, Symmetry.
Powell, Bonnie, Ed.; Myers, Donald E., Ed.
The Minnesota School Mathematics and Science Teaching (MINNEMAST) Project is characterized by its emphasis on the coordination of mathematics and science in the elementary school curriculum. Units are planned to provide children with activities in which they learn various concepts from both subject areas. Each subject is used to support and reinforce the other where appropriate, with common techniques and concepts being sought and exploited. Content is presented in story fashion. The stories serve to introduce concepts and lead to activities. Imbedded in the pictures that accompany the stories are examples of the concepts presented. This unit presents a fundamental geometric concept of rigid motion. Two types of simple motion are presented to help children to find what patterns are unchanged by these motions; the two forms are simple translatory symmetry or repeating patterns, and bilateral symmetry or mirror reflection. In the process, children discover a number of geometrical relationships. This unit will provide the initial formative concepts necessary for various operations with symmetry. Worksheets and commentaries to the teacher are provided and additional activities are suggested. (JP)
