Hi,
I am currently an educ. student, but I came along your post and I just wanted to let you know that you should definitley do memory boxes with your students! When I was in 5th grade each student in my class made one. We included pictures, newspaper articles, writing samples, drawings, etc. We also each worte a letter to 2 students in our class which were sealed and placed in his/her box. Our teacher and principal also wrote us letters which were sealed and placed in the box. We then sealed the shoe boxes with ducktape and wrote all over them "Do not open until 2003" (2003 was the year we would graduate from highschool) Surprisingly, most of my classmates waited until 2003 and then opened their box. It was so much fun and very special to relive all of those memories, and especially to read the funny letters from my classmates at the time!
