I started this lesson by showing the students photos of the houses in New Orleans. These houses tend to be tall, but not wide. We also noticed how bright and colorful the houses are. (I found lots of images on google to show them.)
We started by drawing a large house build out of rectangles (rulers were optional). I showed the students multiple ways to draw windows and doors. Also, I encouraged students to add porches, or balconies, or other details to their pictures. We outlined everything with black crayon and painted with watercolors.
