What's the VALUE of a winter sky?

4th grade began their winter sky value study this week.  Value is the lightness and darkness of an object.  After seeing a similar painting on Pinterest, I decide to teach value and color mixing to 4th grade using this beautiful night time sky scene.  It's perfect for a winter's night, don't you think?  We first drew a circle for the moon, then starting with white, we gradually began mixing varying shades of blue then purple and lastly, black.  More pictures to come as they are completed!
