Structure Sort Worksheet

About This Worksheet

This Grade 7 Language Arts worksheet helps students tell the difference between a phrase and a clause. A phrase is a group of related words that does not contain both a subject and a verb, while a clause does contain both. Students study underlined word groups inside complete sentences and decide which structure they see. For example, “under the bleachers” is a phrase, while “because the volcano erupted” is a clause.

Learning Goals

The main goal is to help students recognize the building blocks used to create longer sentences. Students should already be able to identify subjects and verbs in straightforward examples. This activity moves them toward checking whether an underlined group expresses an action with its own subject or simply adds information. It supports CCSS.ELA-LITERACY.L.7.1, which focuses on sentence structure and command of standard English grammar.

Student Tasks

On this worksheet, students will read ten sentences and examine the underlined group of words in each one. They will label every example as either a phrase or a clause. The sentences include time, place, reason, and condition details, so students see the structures used in several different ways. They must look inside each underlined section rather than judging it only by where it appears in the sentence.

Common Challenges

Some students may assume that every long group of words is a clause. Others may notice a verb-like word but overlook the fact that the group has no subject of its own. Prepositional phrases and dependent clauses can be especially easy to confuse because both often add extra information. Encourage students to underline the subject once and the verb twice whenever they believe the group is a clause.

Teaching Suggestions

A teacher can begin by writing one phrase and one clause side by side and asking what the second example contains that the first does not. Students can then use the “subject plus verb” test on every item. At home, a parent can read the underlined words aloud and ask whether someone or something is performing an action inside that group. This simple check makes the difference much easier to understand.

Worksheet Features

The worksheet includes ten sentence-based examples with the target words already underlined. Its mix of clauses and phrases prevents students from relying on one repeated pattern. Short answer lines keep the work focused while still requiring a decision on every sentence. This page works well for introductory instruction, homework, small-group review, or a quick grammar assessment.
