Look at the fantastic notice board the JRSOs at Whitehalls Primary School in Angus created! A noticeboard is a great place to raise issues and make others aware of what is going on.
Why don't you create a Decade of Action notice board. You could choose another counrty to investigate and look into the issues they face with road deaths. Put your findings on the notice board so other pupils in your school can learn about it too. You could also hold an assembly on the topic.
Good luck and have fun!
Remember, let us know about your great work to get it featured on the Spotlight on or Decade of Action pages!
