----------------------------Original message---------------------------- I am assisting in putting together a weekend session at the Virginia Science Museum concerning cartography and general map literacy and concepts. Does anyone know of sources or articles describing map worksheets for grade levels, age groupings, etc? Having worked in cartography for 22 years, I'm not really adept at anticipating the needs of the relative neophyte in this field. thanks, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Ted Samsel..TBSAMSEL@QVARSA.ER.USGS.GOV..(use if dg11svarmd.er.usgs.gov is not responsive) Personal opinion or observation only.....
