I'm getting ready to write out a new PLAAFP for Aidan, but in the meantime, the above shows that he can use a keyboard AND knows alphabetical order -- with the exception of that missing "U".
Hooray, Aidan! He did this all by himself on my word processor -- it was his own idea, not an assignment -- and was so happy. He had me print it out and is now showing it to everyone in the family. I love his attitude.
(Later on, he did the alphabet several times with his magnet letters, and he's getting the U in there even though I didn't correct him)
