Revising our writing with a partner

Did you know that 40% of writing time should be spent revising?  Only 20% of your time should be writing the first draft, and 40% should be spent at the beginning planning and gathering information.  Because revising is such an important part of the writing process, we spent a long time doing that last week.  Students had a checklist and a partner to work with.  Once they went through the checklist, they picked a couple things to add in order to improve their writing.  We're working on writing an article about magnets for a scientific magazine geared towards kids in grades k-3.
