Thanks for clarifying! I teach year 6 and no, we do not teach anything about it. We have to be very careful about keeping to the guidance - not sure if you have read it but it's worth a look. We stick to that completely and all primaries in my area do. If a pupil asks a question about it (or anything else not in the guidance) we'll explain that's not in the guidance for us to teach but that they will learn more about it as they get older. We'll also contact parents if we were concerned.
This is from the TES:
Teachers must not "reinforce harmful stereotypes" by suggesting that children might be a different gender based on their personality or fashion choices, the government has said.
New guidance on how schools can plan their relationships, sex and health curriculum, published today by the Department for Education, also states that some secondary content may be taught in primary schools, with parental permission.
The section of the guidance entitled "ensuring content is appropriate" states that schools should not work with organisations which produce materials suggesting that "non-conformity to gender stereotypes should be seen as synonymous with having a different gender identity".
As the pp said, we do teach lots about traditional gender stereotypes and 'roles' now and through history, and how we can challenge these.
