teaching children about gender variance
When dchin and epeck read us And Tango Makes Three on Thursday, I mentioned a webevent, created by a student in the core course in gender studies last semester, which might interest you all: it's about Making Sense of the "Gay Penguin" Controversy, and it questions the wisdom of "anthropomorphising animals to contribute to a conversation about human" behavior.
If you are interested in thinking some more about (and creating new) texts to teach children about gender variance, you might find inspiration in a couple of other projects created for that class; see, for example,
Mommies, Daddies, Families,
A Rainbow of Sex Difference,
The Stories We Tell Ourselves and
A Handbook for the Boy Scouts of America....
