My CT told me an idea she heard from a 4th grade teacher in our school and I thought I would pass it along to everyone here. I'm a student teach in a 1st grade room so this couldn't work for me. The 4th grade teacher had students write a letter to themselves that would be read 10 years from now. Basically, they would be writing a letter to their future-selfs. They could write what they think they'll be doing 10 years from now, how they are feeling at that moment, etc. The teacher would hold on to those letters and mail them to the students 10 years later. Anyway, he just mailed those letters to students from 10 years ago. I thought that was a really good idea, but you could always alter it to 5-7 years instead.
