This powerpoint uses authentic pictures of school lunches from around the world to provide cultural comparisons. Students watch a youtube video and then are asked to talk about what school lunches consist of around the world. There is guided (speaking and writing) practice throughout comparing the school lunch pictures. You can use each slide as speaking or writing.
The resource uses this buzzfeed video to engage students: https://www.youtube.com/watch?v=Po0O9tRXCyA (no spoken language, but written English) as well as photos of school lunches from the Huffington Post: https://www.huffingtonpost.com/2015/02/25/school-lunches-around-the-world_n_6746164.html
