This is the generic wording from a Jigsaw leaflet:
In one lesson for 10-11-year olds, children are introduced to the word ‘transgender’ so they understand what it means. This lesson has a focus on prejudice and discrimination where a transgender example is used. The Equality Act is also explained in an age-appropriate way. Being transgender is discussed in the following terms:
Most people are not transgender. A transgender person doesn’t feel their body matches with their gender. Let me explain…a person who was born with a male body may feel they are female, and a person born with a male body may feel they are a female. There can be all sorts of reasons why this happens. Some transgender people choose to change their appearance or body so their gender matches with how they feel. This is called transitioning. Not all transgender people choose to do this though. (If children want more detail, teachers are advised to explain they will learn more about transgender people in secondary school and they should return to the focus of the lesson which is about prejudice and discrimination).
Jigsaw’s decision to include this lesson was partly prompted by requests from schools who have pupils of primary age that have been identified as transgender, or are undergoing transition. Primary schools with a transgender pupil needed a lesson to help the rest of the class understand and empathise with their trans classmate. Jigsaw’s decision was to include this lesson as a matter of course within the Year 6 (Age 10 -11) materials so children understand what being transgender means, in line with the Equality Act. But, if a school needed to use the lesson in earlier years (because they have a trans pupil in a specific class), they are free to do so and should adapt the lesson accordingly for the appropriate age group.
This lesson does not promote transgenderism as a preferred lifestyle. It simply explains what being transgender is, and how some people who are trans face unfair prejudice and discrimination, in the same way that other people do e.g. through racism, ageism, sexism and prejudice against people who are disabled.
