Check out this super cool activity I made for your students. On the first part they must conclude which cities are which on the westward expansion map. Then they need to drag and drop the NFL teams to the correct cities on the map. In the second part students demonstrate their knowledge of the areas of territorial expansion by analyzing the location of these cities and interpreting which territory each team comes from.
No they are not the team logos you are used to. In order to avoid any copyright infringement I did make my own little logos for each team.
This activity would also be great in a Digital Interactive Notebook or even printed and used as a cut and paste interactive notebook activity.
