The writing group is for those interested in designing, developing, trialling and disseminating teaching ideas and resources focused on teaching maths for social justice. The first writing group meeting took place at UCL Institute of Education on 22nd January 2022 and was attended by 14 members of the network. We identified three ideas to develop and divided ourselves into three ‘design groups’ to work on these ideas over the coming months. The plan is for each design group to meet online to refine their idea, pilot aspects with students and develop the idea into an activity ready to be trialled more widely. We aim to circulate these activities to all TMSJN members to trial in schools/colleges in the Summer Term.
