What kids practice
Relative pronouns (who, whose, which, that) and relative adverbs (where, when, why) join extra information to a noun, like "the girl who lives next door." A prepositional phrase starts with a preposition such as under, after or with and ends with a noun or pronoun, like "under the bed." Prepositional phrases tell where, when or how something happens. Both help fourth graders write longer, more detailed sentences.
Watch for
- Using which for a person, like "the man which fixed our sink."
- Mixing up who's and whose.
- Using where for a time, like "the day where it snowed."
- Stopping a prepositional phrase too soon, before the noun.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full relative pronouns and prepositions guide for 4th grade.
