Lesson Plan: Calder's Balancing Acts
Select a lesson plan:

Alexander Calder, Vertical Constellation with Bomb (detail), 1943

Time: Two class periods

Grade levels

Elementary activities: 2–5
Intermediate activities: 6–8

Learning Connections

Math: number sense, equations, addition, multiplication, balance, patterns and sequences
Visual Arts: three-dimensional art, sculpture, mobile, balance, asymmetry

Objectives

Students will:

  • learn the vocabulary of contemporary sculpture and be able to distinguish between abstract and realistic sculpture, mobile and stabile, biomorphic and geometric.
  • write equations using Calder's mobiles
  • learn to recognize mathematical patterns in art and nature
  • build a Calder-style mobile online and/or offline with art supplies

Vocabulary

Sculpture, mobile, stabile, maquette, abstract, realistic, biomorphic (see glossary for definitions)

Materials

For the mobiles: wire, string, paper clips, cardboard, heavy-weight paper, scissors, glue, string, poster paint, markers

Lesson Implementation

Meet Calder online:

To whet students’ appetites for the art of Alexander Calder, have them begin the online lesson. Tell them to do the Quick Calder Quiz, to read his short bio, and to watch the Calder Circus video clip (linked from the short bio).

Classroom discussion:

Tell students that they will discover math in Calder's sculpture when they return to the online lesson. In class, you will focus on his artistic innovations in a group discussion.

As a class, visit this online gallery.

Tell students that these works of art have much in common. Ask them to look carefully, to compare and contrast the images, and then list their comments on large chart paper. Prompt students to investigate each work of art with regard to the following characteristics:

  • two-dimensional/three-dimensional
  • a painting/a sculpture/other medium
  • material: metal, wood, bronze, paper, wire, canvas, paint
  • color: natural for the subject or symbolic
  • is the subject recognizable? abstract or realistic?
  • year of creation
  • What conclusions can you draw? What is new and different about Calder's horses?

Now compare and contrast Calder's stabile Cheval Rouge to his mobile Untitled using the above criteria and have students clarify what is different about this work of art. Discuss the term mobile. How does the innovation of movement change the work of art? (movement introduces a continually changing composition)

  • Has Calder created a whole new art form?
  • The mobile is called Untitled. Why do you suppose Calder gave the stabile a descriptive name (Red Horse) but left the mobile without a specific title? Ask students, "What does the mobile remind you of?" (possible responses: birds in flight, wings, feathers, leaves on branches, flower petals, fish scales, a skeleton, clouds, stars, and planets)
  • Tell students that Calder's sculpture is abstract but based on life forms. The term for this type of abstraction is biomorphic.

Calder online math lesson:

Have students read and follow instructions for the online activities.

Make a mobile

Online, wih the interactive "Mobile Maker"

  • Have students build and rotate mobiles with the Mobile Maker.
  • Optional: have students write and exchange mathematical problems based on their mobiles.

Offline, with art supplies

Have students:

  • read Calder's mobile-making method.
  • think about what they want to express with their mobiles before they begin working with materials.
  • cut and paint shapes.
  • layout wire and shapes on a table or flat surface.
  • experiment with adding/subtracting materials to make the mobile balance.
  • write a title for their mobile.
  • use string to hang it from the classroom ceiling.
  • Optional: have students write and exchange mathematical problems based on their mobiles.

Assessment

  • Evaluate each student's level of participation in class discussion.
  • Assess each student mobile.
