This is a project that I've had good luck with in the past, and the beginning of the year always seems like a good time. I did this with the K-1 class, and it involves them writing their name in block capital letters with black marker and coloring in the "in-between spaces" with different color crayon, to look like stained glass.
It is surprisingly challenging for these 5-7 year olds, but teaches them about negative space, line and patience!
