About this resource

Description

A compound subject is what a sentence has when two people or two things do the very same thing. When a child writes Luke rides the bus to school and then Valeria rides the bus to school, two short sentences say one idea twice, and the writing starts to sound choppy. Joining the two subjects with and fixes it in a single move, and knowing how to take that sentence apart again is just as useful. The Rewriting Compound Subjects Worksheet gives third graders practice in both directions.

This printable Rewriting Compound Subjects Worksheet has two parts on one clean page. In the first part, four numbered items each show a pair of sentences that share the same predicate, such as Cows graze in the green field and Horses graze in the green field. Students read both, then write one new sentence with a compound subject on the wide handwriting line below, changing the verb where the joined subject calls for it. In the second part, two sentences already carry a compound subject, and students rewrite each one as two separate sentences on the pair of lines provided. That is eight sentences written in all, so the skill is practiced forwards and backwards on the same page.

What’s Included

  • 1 print-ready PDF worksheet
  • 4 combine-the-sentences items, each with a writing line for the new compound subject
  • 2 rewrite-as-two-sentences items, each with two writing lines
  • A complete answer key on the final page

There are three reasons this 3rd grade compound subjects worksheet helps children learn the skill. First, it is built on real pairs of sentences rather than on labels, so students discover the compound subject by using it instead of by naming it. Second, the two parts run in opposite directions, which means a child who has only memorized a pattern has to stop and think about what the subject of each sentence actually is. Third, several items quietly ask for subject and verb agreement, so rides becomes ride and builds becomes build once the subjects are joined, and that habit carries straight into their own writing.

Teachers and parents can stretch this lesson in a few easy ways. Ask students to hunt through a favorite chapter book for one sentence with a compound subject and copy it onto a sticky note for a class chart. Have partners each write a short sentence about themselves, then trade and combine the two into one. During writing workshop, challenge students to find two neighboring sentences in their own draft that share a predicate and join them. A quick sorting game also works well: read a sentence out loud and have the class hold up one finger for a single subject and two fingers for a compound subject.
