My students last year loved having whole class journals to write in. They had a chance to write in them during Work on Writing, and a chance to read them during Read to Self. I made up a new set of 8. At the moment they are pretty plain covers, but once a student writes in it they have the option of choosing a sticker from my collection to place on the front cover. The stickers show me how many kids have tackled each topic.
Have the students make their writing "more colorful" by using paint strips. Write a boring adjective at the bottom of the paint strip on the most boring color. Give each student a paint strip and they can use a thesaurus or a word wall to think of "more colorful" words for their strip. Put the best word on the brightest part of the strip. Hang all of their strips on the door and they can use those words to help "make their writing colorful!"
This is part of the free editing set from First Grade Wow. For kindergarten, I use it to show what they can do (smiley face in the check box) and what their newest personal challenge is (I highlight the check box). They keep it in their writing folders. It helps differentiate learning and gives each student focus. There are many other useful pages in the packet, too. All free!
