Hi Mich
I found starfall.com really awesome for this kind of thing - not for the punctuation per se but the techniques of reading and syllables, vowels, the rules and things were done well. plus it was in small digestible clumps so you easily do a big batch or just a little and go back and do some more. Also, DS really liked those 2 piece puzzles where you have a picture on one side and the wording the other or other forms of matching pairs. There was other stuff too which I am just blanking on, but DS was both an early reader and very interested in the how and why of language, I'll post again if I can remember, I really wish I had written more stuff down! And it's was only 3-4 years ago!!

Ps really like the idea of the different fonts, DS was always really interested in signs.
