A lot of the curriculum we used for the puberty unit of our Human Sexuality 101 group was adapted from “Teaching Sexual Health“.  They are a group out of Canada that provides support for teachers and parents.  I used their general curriculum but they also have a curriculum for students of differing ability levels.  They have great resources for parents including “webisodes” that give examples of parents talking to kids about sexuality topics.  The website is very well organized and easy to use!
