One of the Ph.D. students in my Matthew class has this website where he has developed a Bible Map program that allows you to edit the map just about any way that you would like. Today in class the student showed some of the maps where he marked them according to the story of Matthew 21:1-11.

Once you get the map situated the way you like, you can use the image in a Powerpoint slide with a screenshot. On a PC, screenshots can be created by simultaneously pressing the ALT+Print Screen buttons; then paste the image into your document and/or slide. If you scroll the map far enough, you can even get a screen shot of the UK.
