QUESTION 1
What is an organic shape?
A free-flowing shape, like a leaf, cloud, or puddle, often found in nature.
QUESTION 2
Where do you see geometric shapes?
In things with clean edges, like windows, tiles, signs, and buildings (answers vary).
QUESTION 3
Name one geometric and one organic shape.
Geometric: a square; organic: a leaf shape (answers vary).

Create: a shape collage.

Have students cut geometric and organic shapes and arrange them into a picture, so the two kinds of shapes become something they use. A printable shapes worksheet is in The Arts library.
