Counting Grid Squares
On a grid map, you can measure distance by counting squares! If you move from A1 to A4, you moved 3 squares North. If you move from A1 to D1, you moved 3 squares East.
But what if you move diagonally? Moving from A1 to B2 is a diagonal step. Diagonal steps are a little LONGER than straight steps (about 1.4 times longer, if you want to get technical).
For our treasure maps, we will count each step as 1 unit. So a path of 3 North + 2 East = 5 steps total. The pirate would need to walk 5 units to get there.
This is real math in action! You are adding distances together to find a total. If each grid square represents 10 paces, then 5 squares = 50 paces!
