Alrighty! here is some blind contour drawing. The idea is take a sheet of white contructions paper (or paper that wount just crimple up after gettting a little wet) then have the student take a crack at drawing an image on to the contruction paper without looking with a white crayon or pastel. once finishing the blind drawings the student wet the paper with water then fill in the paper with color, bringing the images out in white. really, really neat idea.
    An activity that would be sweet, would be to practice emotions through coloring. take the sheet of paper and divide it into 4 sections with black outlines. then in each box have the students write an emoiton in a certain box then have them draw what they think is angry lines  or happy lines. then have them do this for the other three boxes then color it so they get to see what they think emotion looks like in the form of a line.
