How's this for answering your own question. . .
*Highways To Adventure--student book reviews
*Plan Your Route--goal setting for the beginning of the year
*Map It Out!--goal setting
*Side Trips--for a regions study, what vacation areas (national parks, museums, etc.) are in each state OR create a webquest for the kids to discover what points of interest are in each state
*Travel/Traveling the Reading Highway--for each state, find children's authors who grew up there--how did growing up in that area influence his/her writings?
*Interstate Travel-Each student uses a US map to tell what states you would travel through to get from point to point--what different routes are there to get there--what is the fastest?
*Book A Flight--students choose from a list of books to do buddy reading or lit circles
*Daily Transportation--list/graph of how each student gets to school each day
*Safe Travel Tips--show students how walking in the hallways is like driving. . .stay on the right; show students places that are "No Passing Zones" (stairs, for example); running in hallways earns a speeding ticket (go back to place of origin and do it again safely)
*Rest Area/Stop--spot in the room where students can work, read, think, chill out quietly
*Construction Zone--project area of the classroom, supply areas
*Drivers' Licenses--kids bring in photos to create a driver's license at the beginning of the year; student info sheet can be the application for the license
*License Plates--each student creates a nametag for her desk; create a glyph for students to follow in creating each plate
*Vehicle Inspections--inspecting desks; students need a "tune-up" if desk needs reorganization
*Travel Guides--students search classroom library for books about a certain place, state in US to create a book basket/display
*Mystery Destination--coop team creates clues/directions for finding a certain state on the map
*I Have. . . Who Has" game about the states or cities in your state. Example question: "I have Pittsburgh. Who has the "City of Brotherly Love"?"
*Travel Games--games that can be played in the car adapted to the classroom
