`Same Symmetry:Ruth Goodman                   Walt Disney Magnet School                               4140 North Marine Drive                               Chicago IL 60613                               (312) 534-5841Objectives:Grade 5 (1) Students will develop an understanding of symmetry and a sense of geometry.  (2) Students will identify lines of symmetry in a geometric figure. (3) Students will see that elementary geometry should be informal and allow for      exploration of ideas.  (4) Students will learn about the history of quilts. (5) Students will create a symmetrical quilt.Materials Needed: (1) Scissors                 (5) Cuisenaire rods (2) Crayons                  (6) Mirrors (3) Tape                     (7) Two large poster boards (4) Graph paper              (8) PlaydoughStrategy: (1) Teacher will show objects to the class and explain that their structure      relates to a mathematical term in geometry.  (2) Teacher will review the terms congruent and similar.  (3) Students will look for symmetrical objects in the room with vertical or      horizontal lines.  (4) Pass out playdough and paper with geometric shapes. (5) Students will make geometric shapes with the playdough and show lines of      symmetry on the paper and the playdough shapes.  (6) Pass out mirrors and papers for mirror symmetry. (7) Explain mirror symmetry and complete paper. (8) Pass out cuisenaire rods and graph paper. (9) Using the rods and graph paper, students will make a design on half of the      graph and then color the other side exactly like the rods. (10) Teacher will talk about the history of quilts and show a book.(11) Then in their groups, the students will each design, name, and color their      quilt pattern.  Performance Assessment: (1) Students will locate pictures from magazines that demonstrate bilateral and      radial symmetry.  (2) Students will design a quilt pattern with two lines of symmetry.References:Platts, Mary E, Intermediate Mathematics Challenge. Educational Service, Inc.
