Language
The Language domain of the Grade 3 OST ELA covers grade 3 conventions and vocabulary. You will choose correct verb forms, pronouns, punctuation, capitalization, and word forms, and you will use context, affixes, and dictionary entries to figure out meaning. Questions often look like a sentence with one underlined choice; read the whole sentence before deciding.
Conventions to know
- Subject-verb agreement: a singular subject takes a singular verb; "each," "everyone," and "nobody" are singular.
- Pronoun-antecedent: a pronoun must match its noun in number and gender; "Maya lost her glove."
- Verb tense: simple past, present, future; keep tense consistent.
- Comparisons: -er/-est for short adjectives; more/most for longer ones; do not double them.
- Conjunctions: and, but, or, so, because, although.
- Capitalization: proper nouns, titles, days, months, holidays; not seasons.
- Punctuation: commas in addresses and dates; quotation marks around spoken words; apostrophes for possessives.
Vocabulary tools
Context clues are words nearby that hint at meaning. Affixes change meaning: un- means not, re- means again, -ful means full of, -less means without. A dictionary entry gives pronunciation, part of speech, and meanings; choose the meaning that fits the sentence. Shades of meaning matter: "stroll," "walk," and "march" are not identical.
Worked example
Sentence: "Each of the hikers (carry / carries) a map." Reasoning: the subject is "Each," which is singular, even though "hikers" is plural. The verb must be "carries." The nearby plural noun is a trap. For vocabulary: "The trail was so steep that even the goats seemed tired." Steep means sharply sloped, because the goats' tiredness signals a hard climb; "long" and "rocky" are not supported.
Traps that cost marks
Matching a verb to the nearest noun instead of the subject; putting the apostrophe before the s in a plural possessive; capitalizing seasons; choosing a word that sounds right but does not fit the context; adding -er to a word that needs "more."
