This activity could take place in the museum or in the classroom. It is differentiated so educators can decide how best to adjust the level of instruction to fit students' abilities.
Objective: Students will become familiar with vocabulary (angle, protractor, alignment, right, acute, obtuse). They will question how artists use line and measurement to create compositions. They will measure and create angles. For more ideas, see: Geddes Lesson Plan.
1. How are angles used in daily life?
Demonstrate how a protractor is used. Allow students to experiment.
Activity: Print or project Frank Stella's lithographs and ask students to measure the angles using protractors.
Ask them to adjust the angle of the V and reconstruct the artwork. How does changing the angle change the composition? Is it as effective?
Alternative: print Frank Stella's compositions and ask students to alter the color of the shapes, or to use them as coloring pages. How elements of art, such as color and line, contribute to the success of the work?
How do math and art properties combine here to create an interesting composition?
