Over 40 powerpoint slides I use in with my French 2s or higher. Nearly every week we have "une note culturelle". Students keep records of their notes and at the end of the year there is a note culturelle quiz, which is also on my page (for Free!). Please note that the powerpoints start off in English but progress to French since these slides are geared towards level 2 and above.
There is a French 1 note culturelle powerpoint I have where the notes are in English.
