Although the concept of symmetry is introduced as early as first grade, it isn't until fourth grade that assessment indicators involving symmetry are listed in most standards. At this point, students build, draw and analyze the various properties of two-dimensional shapes. Within geometry this includes the study of lines, angles, classifying shapes, and recognizing and identifying lines of symmetry. The Designing a Flying Disc template provides the ideal assessment for the symmetry standards.
Editor's Note: This blog is part of a series of posts from former math specialist Scott Loomis on the real world math templates he has created for Wixie and how you can use and modify them for your own awesome performance tasks. You can read the backstory on his experience and expertise below.
Design a Flying Disc
This Design a Flying Disc template includes a three-part progression of symmetry skills (1) Identify lines of symmetry, (2) Justify a provided line of symmetry as correct or incorrect, and (3) Create a flying disc design that includes at least one line of symmetry. The teacher may opt to make a few of their own designs that the class can complete as a whole as an introduction to the skill before students begin. Otherwise, the task is rather straightforward.
Grade: 4 (2 in Virginia)

Math Standards and Learning Goals
Common Core Standards - Grade 4 Mathematics - Geometry
4.G.A.3 Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts, Identify line-symmetric figures and draw lines of symmetry.
Virginia Standards of Learning - Mathematics - Measurement and Geometry
2.12 The student will a) draw a line of symmetry in a figure; and b) identify and create figures with at least one line of symmetry.
Texas Essential Knowledge and Skills (TEKS) Geometry and measurement
TX.M.4. The student applies mathematical process standards to analyze geometric attributes in order to develop generalizations about their properties. The student is expected to:
(B) identify and draw one or more lines of symmetry, if they exist, for a two-dimensional figure
Wixie Skills Review
The first page of the template requires students to use the line tool from the Shape tool menu. Students should choose a color for the line that does not blend with each design. Complete directions for drawing and modifying lines in Wixie can be found in the Help menu, via your profile image in the upper right hand corner. Select Skills > Painting > Paint a line.
Page 2 requires students to utilize the microphone tool to justify their belief that the given line is or is not a line of symmetry. Complete directions for this process is also in the Help menu. Skills > Pages > record a Sound
Page 3 requires students to create a design that includes at least one line of symmetry. This task is easily accomplished with the paint tools. Some students may also use the Image button to add pictures from the Stickers library. Review the paint tools and image options, including parameters as to what they can and cannot use.
