Summary of Activity
Students will find two-dimensional geometric shapes in their environment that have symmetry. Students will draw a geometric shape and divide it with a line of symmetry. Students will create a painting using geometric shapes that demonstrates symmetry.
Participate in a classroom discussion of student observations of shapes in the painting by Roger Brown and the use of symmetry in this work of art.
Find symmetry in shapes around the classroom.
Draw a geometric shape and accurately draw a line of symmetry.
Sketch the shapes.
Create a picture using geometric shapes that are symmetrical.
Present reproduction of Mountain Sites by Roger Brown to the class and provide information about the work and the artist. Facilitate a discussion about the visual elements of the work with an emphasis on how the artist used a repeating shape in this piece to create the image of a mountain range. Introduce the word symmetry and explore how the mountain range itself and the individual mountains are symmetrical. Introduce the phrase line of symmetry and demonstrate how it divides a mountain in half so that both sides are the same size and shape.
- After the class discussion, ask students to look around the classroom for other geometric shapes. Ask them to draw an imaginary line through the center of each shape so that both halves are the same size and shape.
- Ask each student to then use a pencil and a pattern block template (or ruler) to duplicate the shape on paper. Then, using a ruler, ask each student to divide the shape in half using a line of symmetry.
- During the next class period, instruct student to use sponges that have been precut into simple geometric shapes to create a symmetrical picture. Fold a piece of paper in half to demonstrate how to create a line of symmetry for the picture. Instruct students to dip their sponges in tempera paint and then stamp both sides of the paper with the same sponge shape to create a symmetrical image.
