I stumbled across a new art teacher supply this summer.
Back in the spring, my mom e-mailed me about a great sale on Crayola products. Not knowing what would be in stock at the local arts and crafts store, I sent her a dream list compiled from Crayola's website. I had never heard of Dry Erase Crayons but thought they would be neat to try.
I think I am in love.
I demonstrate many art skills on the whiteboard directly, but cannot model value changes due to pressure and layers. While I absolutely hate using chalkboards, I hear that's one thing they were good for...
So art teacher, meet Crayola Dry Erase Crayon. It comes in standard colors and brights (works on whiteboards or black dry erase boards). And just to show the value changes possible, I made a quick shaded sphere for you. I also demonstrated the standard green next to the bright green, then two oranges and two purples.
Thus far, a little elbow grease and a soft cloth has been all that's needed to get erase the crayon.
But for now, I am content to be able to demonstrate creating value with pressure and/or layering on my whiteboard!
And as for you, run, don't walk, to your nearest arts and crafts store to pick up a teacher box of these crayons. If you have the time, energy, and ideas, consider picking up more for your class, but at least buy yourself a set for demonstrations...
