Chapter 2 introduces graphing, linear equations, and Buried Treasure games in the Cartesian Coordinate Plane. You'll solve puzzles using what you have learned about the rectangular coordinate system. The chapter has a special review appendix on linear equations. The chapter concludes with a hunt for pirate treasure buried on tropical islands with the help of coordinate geometry.

If choosing chapters randomly instead of going through Pirate Math sequentially, I suggest you browse through the whole book contents preview once to see where certain topics are introduced before you begin. If the math review is extensive, linear equations for example, then the material is placed in an appendix.

One of the goals in Pirate Math is to teach graphing. There are games teaching graphing in the coordinate plane (Chapter 2), using polar coordinates (Chapter 3), on a spherical surface (Chapter 4 longitude and latitude), and in three dimensions (Chapter 5). Pirate Math also contains a collection of puzzles that help develop reasoning and problem solving, which is at the heart of all mathematics.
