A Message in Points

Develop coordinate plotting and locating skills

In this exercise, you provide a secret message (between ten and sixty letters and numbers, not including spaces, but no punctuation) which is shown as empty boxes at the bottom of the page. Each box has a grid coordinate. The grid is filled with labeled points. To fill in the boxes, the student matches the coordinates with the labeled point and fills it in. When all boxes are filled in, the secret message is revealed.
