Pupils as young as seven are being encouraged to wave rainbow flags and wear a badge which displays whether they use male, female or non-binary pronouns.
The Mail on Sunday has seen lesson plans which reveal children in Key Stage Two – which covers seven to 11-year-olds – are taught about being non-binary.
The lessons are being rolled out as part of Schools Diversity Week, which is run by LGBT charity Just Like Us in the last week of June.
More than 6,000 primary and secondary schools have signed up. Andrea Williams, of Christian Concern, said: ‘Thousands of children will be indoctrinated with extreme gender ideology this summer without the knowledge of their parents.’
Just Like Us did not respond to a request for comment.
