Pablo Picasso, Georges Braque and Juan Gris all used collage in their work. Students construct collages whose elements are factors of composite numbers. In the course of the lesson they learn about or review the differences between prime and composite numbers.
Although this illustration may look like a painting or drawing, it’s actually a reproduction of a collage. A collage is a composite, or collection, of shapes that have been glued to a flat surface. Some artists who constructed collages based much of their art on the shapes created from a perspective drawing of a cube or other geometric solid. This was called Cubism, a style of painting and sculpture developed in the early 20th century that reduced natural forms to their geometric equivalent. It was often influenced by African Art.
