What This Standard Means
What Students Need to Do
- Students find conjunctions, prepositions, and interjections in sentences. They name each word’s job and explain how it connects ideas, shows relationships, or adds emotion.
What Mastery Looks Like
- Students correctly identify these words in varied sentences and describe what each one does. They explain how a conjunction connects ideas, a preposition shows a relationship, and an interjection expresses a reaction.
Common Misconceptions
- Students may confuse prepositions with conjunctions because words such as before and after can serve either role. They may label any expressive word as an interjection or name a word without explaining its job in the sentence.
How to Assess It
- Use this exit ticket: “Wow, Maya waited by the door because the bus was late.” Students identify Wow, by, and because, then explain each word’s job.

Ways to Teach It
Give groups word cards to sort into conjunctions, prepositions, and interjections, then have them build and label three complete sentences.
Ask students to explain how the meaning changes when because becomes although in the same sentence.
Play a sentence relay where teams add a fitting conjunction, prepositional phrase, or interjection to a sentence stem.
Have students highlight examples in a classroom notice, recipe, or sports article and write what each word adds.
