Mission: Numbers stick when you steal them from the city. Next U-Bahn ride: photograph a line number, a price, and a house number. Write them as words here first.

Reminder: 21 = einundzwanzig (one-and-twenty). Unit + und + ten.

Write the numbers in letters (lowercase is fine).

📱 Phone mission:
  1. Photograph 3 numbers: U-Bahn line, ticket price, time (e.g. 17:42).
  2. Voice-note yourself reading them: “Linie siebenundvierzig, drei Euro zwanzig...”
  3. Send photos + voice note to class chat with caption “Meine Zahlen!”
🔥 Viral loop: Duel a friend Send one photo with “Wie heißt diese Zahl auf Deutsch?” If they answer in 60 seconds, they pick the next photo. Fastest duel in class gets posted (with permission).
