I changed to...
I used to always do this with my fifth graders, at the beginning of the year, until the day I had one of my big, tough boys break down in heaving sobs. Turns out that his grandfather that he was very close with had passed away over the summer, and couldn't handle the idea of burying anything, even words. So, from then on I have a retirement party at the beginning of the year to retire:
nice
said,
fun,
good,
bad.
We also at that time brainstorm lists for walk, run, happy, important, think, and pretty.
