I did the same thing for my second graders.
Here are the songs I used:
High School Musical; We're all in the together
Cars, Rascal Flatts; Life is a Highway
Meet the Robinsons; We're the kids of the future
Toy Story; You've got a friend in me
Rascal Flatts: My Wish
The kids loved it because they were able to sing with all of them and I made some parents cry with the last song.
