Writing is hard work, requiring active engagement and the highest level of critical thinking skills. Writing  puts a heavy load on our working memory. Many students with learning differences have compromised working memories. Pre-writing skills help  lift the cognitive load that proficient and good writing require. Students must first "anchor" their ideas to make writing less taxing. Organizational notes, such as Notice and Note sign posts,  graphic notes and charts, set students up for the planning and structuring stages of writing. Many students with language based learning differences have compromised working memory, slower processing and/ or word retrieval issues as well. Many students with these learning profiles, as well as those without, benefit from explicit scaffolding techniques to help them:

capture their ideas

organize ideas

create a structure to follow 

Additionally, walking through the process with discussion and sharing, peer and teacher editing sessions yield stronger writing skills, self confidence, expressive language.
