General Activity Information
 Activity ID: 110 Title: Using Symmetry to Create Art Digital Tool/Resource: Symmetry Artist Web Address – URL: http://www.mathsisfun.com/geometry/symmetry-artist.html Overview: Symmetry Artist is an interactive painting activity that allows students to draw on an axis of reflective symmetry or rotational symmetry. Students can customize line style and color. The symmetrical art is printer friendly.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2019 (2019) Grade: 4 29. Define 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. a. Identify line-symmetric figures and draw lines of symmetry. Unpacked Content Evidence Of Student Attainment:Students: Given a shape, identify a line of symmetry. Given a shape, identify the number of lines of symmetry. Given half of a two-dimensional figure on grid paper, draw the other half so that the two sides are symmetrical and include the line of symmetry that separates the two halves. Justify the existence or non-existence of line symmetry within figures by drawing the lines of symmetry.Teacher Vocabulary:Symmetry Two dimensional figure Line of symmetryKnowledge:Students know: Characteristics of lines of symmetry. Skills:Students are able to: Define a line of symmetry for a two-dimensional figure. Identify and draw lines of symmetry for two-dimensional figures.Understanding:Students understand that: a line of symmetry divides a shape into two parts such that when folded on the line, the two parts match.Diverse Learning Needs: Essential Skills:Learning Objectives: M.4.29.1: Identify line symmetric figures. M.4.29.2: Draw lines of symmetry on a one-dimensional figure. M.4.29.3: Recognize lines of symmetry on a one-dimensional figure. Prior Knowledge Skills:Recognize a fraction as part of a whole. Decompose a large pre-made shape using smaller shapes. Compose a large pre-made shape using smaller shapes. Partition a rectangle into rows and columns of same-size squares, and count to find the total number of them. Partition circles and rectangles into two, three, or four equal shares; describe the shares using the words halves, thirds, half of, a third of, etc.; and describe the whole as two halves, three thirds, or four fourths. Define halves, thirds, fourths, quarters, whole, parts (shares) and equal. Distinguish between equal and non-qual parts. Model partitioning circles and rectangles. Decompose pictures made of simple shapes. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.29 Given a drawing of a shape with a line drawn across the shape, identify if it is divided symmetrically.
Learning Objectives:

Students will recognize lines of symmetry in two-dimensional figures.

Students will draw lines of symmetry.

Strategies, Preparations and Variations
 Phase: During/Explore/Explain, After/Explain/Elaborate Activity: 1. Demonstrate the concept of symmetry by displaying images of symmetrical objects and by pointing them out around the room. Ask students to locate examples or give examples.2. Distribute a handout asking students to draw a line of symmetry. These can be printed according to grade level at this site.3. Now ask students to fold a piece of paper in half and try to make a symmetrical drawing using the fold as a line of symmetry.4. After 4-5 minutes of drawing a symmetrical picture introduce students to Symmetry Artist. Point out the different features and ways to customize the drawing.5. Students may create freely or they can be given a challenge. For example, "Students should write their name on a diagonal axis." or "Students should make a symmetrical flower using the rotational symmetry feature." Assessment Strategies: Assess understanding of symmetry using the handout and student's creations on the digital tool. Advanced Preparation: The teacher should be familiar with Symmetry Artist.To strengthen background knowledge of symmetry the teacher can show a PowerPoint based on grade level. A free age-appropriate PowerPoint can be found here. Variation Tips (optional): The Symmetry Art created by the students could be printed out and displayed. Students could be challenged to find the lines of symmetry in the artwork of other students. Notes or Recommendations (optional):
