We read a book called A Pirate's Guide to First Grade by James Preller to set the mood.
We also read a cool book on maps, to review map skills (there were some pages I skipped if it didn't meet the standards for first, i.e. too high): Follow That Map! A First Book of Mapping Skills by Scot Ritchie.

I asked students what pirates and maps had in common to get their juices going. Then, we had a fun time with a map activity I created, where students had to draw maps (focusing on map keys, symbols, and compass rose) to find the treasure! I differentiated among the grade level, so there are actually 3 levels of maps I used: for our gifted class, I gave them the blank map template, then they had to draw their own map key, compass rose, and create symbols. For another class, I provided the map template, map key, symbols, compass rose, and title BUT they had to cut them out and use them in the correct place. A third class received the map with the map key, symbols, and compass rose on it, but had to create a title and draw the symbols from the map key on to the map (and there was a space where they could create more symbols, if they wanted to).
It made for a really fun lesson, so I hope you'll check it out! Click on the picture below to take you to TPT or {here} for Teacher's Notebook.
