I used this drafting booklet with my third graders when introducing the writing unit. To help students with their structure (paragraphing and organization) I have the students draft across pages with a paragraph on each page. If needed, students can jot down a few ideas on the box at the top of each page.
Then when using their draft to writing a final draft, they indent accordingly. Drafting across pages also helps in the revising and editing process as kids have room to write in their changes.
