Hey JoeZ, have you asked this question around in ScratchED? You can try asking around here in the 'Teaching with Scratch' forum, as you're more likely to get an answer from teachers experienced with teaching with Scratch (this forum is used mostly by younger kids).

I do not know about any pre-school teaching on scratch. sorry . But I do however, know about one teacher in Taiwan, who had his/her students remix it for an assignment. But for pre-school, I think it would be more just part of the project that someone could present to them. Maybe I am wrong
. Those are my thoughts.
