I think all of these are fantastic, and not just for the first week back.

Time Line Challenge
Print 10-12 photos from the time period you will be studying. Mix up the photographs and distribute them to random students in the classroom. Have the kids with photos head to the front and hold up their photo. Ask the rest of the class to work with those standing to correctly arrange the photos chronologically. Lead a discussion that allows kids to explain their order and to introduce future content.
It also works great to divide your class in half, give each group the same set of photos and have the two groups create “competing” timelines. Let them argue for the correct order and work to convince students in the opposing group to change sides. You might give extra credit to the group with the largest number of students. Provide the correct order and subtract points for any mistakes made by the “winning” group. Give those points to other group.
Man…I’m tempted to do this one the first day of class…
