Math Connections in Art: Gridding

from Cleveland Museum of Art

Program image

In this four-part series students will learn about the work of American painter and printmaker Chuck Close and will also learn to apply math concepts and skills used by the artist to transfer photographic images to another working surface. Beginning with photos of themselves, students will measure, grid and reproduce their portrait into a painting or pencil rendering which may be finished later at home or in the classroom. Concepts such as proportion, ratio, percent, and area are reinforced.

Program Details


Session 1
1. Introduce works by Chuck Close, an American artist who uses math to dramatically scale his images.
2. Using math principles guide students through the gridding process they will use to enlarge their images for the self portrait they will create over the course of the 4 sessions.

Session 2
Grid photographs students have brought and explain that finished drawing needs to be 50% larger than original photo.

Session 3
Guide students as they use their gridded photos from Session 2 to begin transferring the design to the larger drawing paper.

Session 4
1. Students finish their self-portraits.
2. Review math concepts employed in enlarging their images.
3. Discuss Chuck Close’s work and the way in which he and other artists break color into small shapes for expressive purposes.


Students will understand how Chuck Close, and other artists, use math in creating their art.
Students will use a grid system to help accurately enlarge an image in a work of art.
Students will learn how to determine the size of the enlarged image, based on proportion.
