The first column is about Prewriting- here a student can brainstorm and plan about potential topics. The next column is dedicated to Drafting or organizing the ideas into proper sentences and paragraphs. The third column suggests reviewing and improving the written content. The fourth column is on editing the grammar, checking spellings and punctuations. The last column is about creating the final draft and sharing it.
