On June 7th, 2013 Ruth Edwards and Christian Bokhove ran a “Mathematics outside the classroom” day with PGCE and SKE+ students. On this day students started with a fraction relay, went out do do some readymade outside maths activities, and then used these for inspiration for making their own trails. Every group made a four-node maths trail for Year 10, and in the afternoon the trails were swapped between the groups. A  dedicated page is used for the resources and the results and can be found in the menu under “Activities and projects”.
