Answer:
Conventions are the mechanics of writing, including spelling and grammar.
Step-by-step explanation:
The 6 + 1 Trait Writing Model is comprised by seven key qualities. Teachers use them as a guide to teach students specific skills to improve their written works. The seven traits are: ideas, organization, voice, word choice, sentence fluency, conventions, and presentation. Due to the question we are answering here, the one that matters to us is the trait related to conventions. Conventions are the mechanical correctness of the piece, including spelling, punctuation, capitalization, grammar/usage, and paragraphing. When it comes to conventions, teachers should accommodate their expectations to the grade level and the skills students have already learned. Note that handwriting and neatness are not part of conventions, but of presentation.
