At school I am often doing demos showing technique, medium, drawings etc. I often grab models or students to get a drawing down before I start throwing the paint around. Here are few to give you an idea...
"Eva" (above)
acrylic and pencil
-in-class exercise.
"Julie" (right)
watercolor pencil
-one of my most favorite sketching mediums, great for on the fly or when you can't stay long enough to paint it out... just add water later!!

"Andrew"
acrylic and gesso over ink and pencil
-messy is best, let it ride, go with it!!

"Elizabeth"
gouache over gesso and pencil
-it's all about the light.

"Diane"
acrylics
-quick drawing directly with the paint.
