Social Justice and Global Citizenship are extremely important topics that students from grades 5-8 need to learn about. In a language arts program, a great deal of time can easily be spent on topics related to social justice such as refugees, charities, aboriginal people, and citizens from developing countries.
The following unit has a broad range of activities that I have compiled over the years to help my students understand the importance of being a good global citizen. I would use this unit “buffet style”: take the things that you want and don’t worry about the rest. You have to be comfortable with the content, as well as your students!
