I had a teacher contact me with this question:
I ask students to look through their drafts- keeping ones they may want to come back to and work on- about 5 of those- and the rest go in a storage file that I keep. Kids are so cute when they look through the writing that they did back in September! They can’t believe they “used to write like that”. If you want to add a reflection piece to this assignment- have kids write down some things they “used to do” in their writing that they don’t think they do anymore. Some kids say things like “I used to scribble and now I use my letters” or “I used to not put any spaces in between my words” etc.
What they don’t keep in their folder, you will just file these away- a file folder per kid. You’ll want to hold onto the writing from back in August/September, but you don’t need kids to keep it in their folder all year long.
