Final answer:
A letter-formation guide or sample alphabet is the most helpful support for a student struggling with letter formation during the drafting phase of writing.
Step-by-step explanation:
If a student is struggling with letter formation, the most helpful support to provide during the drafting phase of a literacy narrative would be a letter-formation guide or sample alphabet. This tool serves as a visual aid, enabling the student to directly compare and practice their letters, which is essential for improving handwriting skills. This kind of support can help the student focus on the content of their writing, while also working on their letter formation.
For instance, providing a chart with the correct way to form each letter of the alphabet is useful. The student can refer to this chart while drafting their literacy narrative, which helps them concentrate on expressing their thoughts without being hindered by the mechanical aspect of writing. This assistance is particularly beneficial for students with conditions such as dysgraphia, which cause challenges in handwriting.
