I discovered a huge map resource for teacher/school/student use:
Maps That Teach: Free U.S. and World Maps and Puzzles http://www.yourchildlearns.com/geography.htm
"Maps that Teach take advantage of the fact that geography is spatial. They also utilize the way kids learn best, by actively participating in their learning; learning by doing. As students assemble the maps, they build a permanent mental picture of their world. From Maps that Teach, a student will learn about the continents and where they are in relation to each other; the countries of the world, their capitals and major cultural landmarks, physical features; what is far and what is near."
All kinds of printable maps (world,continents, countries, states, world regional maps,etc), map puzzles, online interactive maps, world atlas, BIG sized maps for download and printing..
Most of the printable maps, are basic outline (not labeled) maps...easy to use and print.
Very user-friendly site for teachers & students!!
