Learning to make maps with GIS is  the most profound way to learn geography. Learning by doing. Learning by making.

Unlike pre-packaged images, creating a map with GIS is also like designing artwork in Photoshop or Illustrator. You control the pen, the color, the thickness of the line.  You chose to highlight the items you want people to see and fade the less important ones.

And if you like math, you can compare areas or geographic shapes, measure distances, calculate angles.
