How the Leitner box works

Every card starts in box 1. Answer it correctly and it moves one box further — and comes back less often. Get it wrong and it returns to box 1 for a fresh start.

Box 1
every day
der Hund
danke
Box 2
every 2 days
die Zeit
gehen
Box 3
every 4 days
schön
Box 4
every 8 days
das Brot
Box 5
