I made this One Piece-themed treasure hunt activity for a lesson on directions.
Everything should be explained in the PPT, but here's the gist of it. This is an activity for groups. Each group gets one treasure map and one "Luffy" (print in color and laminate both the map and Luffy). The teacher has a secret list of destinations (I've included the destinations I used, but use whatever destinations you'd like). Once a group finishes giving directions to one destination, they get the next one from the teacher (this allows you to check their work as they go). First group to finish is the winner.
The printable map could be good for plenty of other things too!
Let me know if you have any questions!
