The lesson plan is not mine. I used part of Y Graignic's lesson and a lesson from a National Board Certified teacher (US). This was offered freely for French teachers on this website. http://madameshepard.com/
Slide 5 i only used with my Advanced Placement class.
For my Level 4/AP classes (not sure what the English equivalent is), I had them do a debate in French arguing the appropriate French response to the crisis. I also had them write messages of condolences in French using si+imperfect + conditional or subjunctive.
I hope this is helpful.
