He did these at school. This one he traced (obviously) and added an extra "C."
Freehand! Ok, he started the "C" too far to the right and had to start back at the left with his "u." Also, the "4" (they said) was under the "r" isn't very clear, but I'm pretty impressed for his first attempt ever!
(However, the fact that I scanned these and posted them on a blog may have already tipped you off.)
ETA: When I picked Curt up this afternoon, I learned this certainly wasn't an isolated incident. He's been writing all week. Even the other kids were bragging on him. Now, if we could eliminate the pinching. I'm off to the middle school football game.
