My boy just got a cheapy paper little stencil given to him somewhere and the novelty of it entertained him with a marker and a pad of paper. Also he likes the dot to dots. They're just a satisfying addition and instant gratification. He likes to pretend word searches right now (he's not really doing it).
Also, I know some people don't like people posting brags about their own kids in other people's threads, but here's a place to bring up this George Washington again. [Linked Image from i945.photobucket.com]. (which one's mine & which one's his, right? lol)
The book is Draw Write Now. I took one legalpad and gave Wyatt3.5 the other. I drew each step on my paper. I told him to do each step with a pencil, then after each step told him to go over the same step with a marker "to make it darker". Use the same process, you'll get the same results. the results being an impressive picture to show for it, not the instant ability to draw what's in your mind the way you want to. That takes time.
