Dominic came into the office spelling out loud and moving his finger in the shape of letters. So I gave him some paper and said "Spell Swiper for me"
And look. After he spelled Swiper, I told him to Spell Dragon2. And he did. :)
This is without ANY assistance or hand positioner. and obviously, no lines.
Then for kicks and grins, I asked him to spell Dora. I've never seen him do that one. And he DID. I had to spell Fox out loud once, and then he did it. And he tried to spell Mom. :)
