Teach UNICEF is an excellent resource for lesson plans and materials on social topics. I haven’t quite figured out the exact way to navigate it — it has an organized collection here, and then they have “Global Citizen Brief” like this one on Syria that appear to be elsewhere on the site.
The lesson materials are top-notch and provide versions based on grade-levels. Some of the student questions in the lesson plans themselves seem a little too UNICEF oriented, so I suspect most teachers will modify them.
I really like how some of the lessons have specific photo and video-based supplements that are useful for all students, and especially for English Language Learners.
Here is how the organization describes itself:
TeachUNICEF is a portfolio of global education teacher resources designed and collected by the U.S. Fund for UNICEF’s Education Department for teachers, afterschool instructors, and parents. The units, lesson plans, stories, videos and multimedia cover topics ranging from the Millennium Development Goals to poverty and water and sanitation.
I’m adding them to The Best Places To Find Free (And Good) Lesson Plans On The Internet.
