Writing
The Writing domain asks you to produce clear, organized writing and to revise and edit it. On the Grade 4 OST ELA test, writing appears in extended responses and in revising and editing questions. You may write an opinion, an informative or explanatory piece, or a narrative.
Match the mode to the prompt
- Opinion: state a position, give reasons, support each with evidence, and answer the other side.
- Informative: introduce a topic, group related facts, use definitions or examples, and end with a conclusion.
- Narrative: establish a situation, introduce characters, use dialogue and description, and show a change or resolution.
Plan, link, and choose words
Plan before drafting. Each paragraph should have one job and a topic sentence. Transitions such as however, therefore, and for example show how ideas connect. Replace vague words such as good or thing with precise ones. In revising questions, reread the sentence before and after a blank so the new sentence fits the whole paragraph; in editing questions, check capitals, commas, quotation marks, and spelling.
Worked example
Prompt: Should recess be longer? Weak answer: I think yes because it is better and kids like it. Strong answer: Recess should be longer because movement helps students focus. A study of fourth graders found that a 20-minute break improved attention in afternoon math. That evidence matters because students return to class ready to learn. The strong version names a position, gives a reason, adds evidence, and explains the link. The weak version repeats an opinion without support.
Traps that cost marks
Drifting off the prompt; listing reasons without evidence; retelling a source instead of using it; writing a conclusion that introduces a new topic; correcting one error while creating a run-on; ignoring directions about length or genre.
