I’ll see if I can find out what happened to the original URL that contained the elementary school curriculum. In the meantime, what about the documentary, It's Elementary: Talking About Gay Issues in School? Here’s a brief quote from New Day Films (presumably a distributor) about the film:

...Rather than focusing on the debate between adults, though, the film takes the point of view of the school children, starting as young as first grade.

The results are surprising ... Third graders' jaws drop when they find out some of their favorite celebrities are gay...

And here’s what the film’s producers, Women’s Educational Media, have to say:

Since its release, the producers have run a remarkably successful grassroots distribution campaign, intended to make It's Elementary accessible to every conceivable type of institution working with children today. Through this effort, the film has had an unprecedented impact, creating a tidal wave of activism and public dialogue about dealing with lesbian and gay issues in schools.

Again, I don’t want my tax dollars funding this.
