I formulated this lesson after seeing Mrs. Sturgill teach something like it at the Frist one summer. We read the story "Roberto the Insect Architect" to inspire us to "Be Creative!"
The students created blueprints and designed a house or building for a bug! After they painted their drawings blue, they sculpted their 'bug' out of model magic. Once those dry, we'll add bright colors.
Here's that worksheet about Architectural Details...I found it in a green book called Art Starters? (I think.)
