And But So Practice Activities
Grade 3 students practice using and, but, and so to join ideas, show contrast, and explain results in clearer sentences.
Practice that builds confidence
What students learn
These Grade 3 grammar worksheets help children understand how and, but, and so connect ideas inside a sentence. Students learn that each word has a different job: adding information, showing a change in thought, or telling what happened as a result.
The printable activities include choosing the best conjunction, completing sentences, combining short sentences, and writing original examples. Each task supports stronger sentence variety within the Parts of Speech section of Grammar and Writing.
Grade 3 writers are ready to move beyond very short sentences such as “I packed my lunch. I forgot my drink.” These worksheets show how connecting words make writing smoother: “I packed my lunch, but I forgot my drink.” Children practice the meaning and use of three common conjunctions: and for adding, but for contrast, and so for a result.
How the skill progresses
Activities often begin with simple recognition: Which word best joins the ideas? Students may then complete sentences like “The sky was dark, ___ we took an umbrella.” Next, they combine two sentences and write their own. This progression helps children think about the relationship between ideas, not just fill in a blank.
Parent practice routine
At home, read one sentence aloud and ask, “Are we adding, changing direction, or showing a result?” Have your child hold up three fingers: one for and, two for but, three for so. Then let them say the full sentence before writing it. Use everyday examples: “I wanted cereal, but the box was empty” or “It was raining, so we played inside.”
Classroom uses
Teachers can use these printables for grammar mini-lessons, writing centers, morning work, partner practice, or quick checks after teaching conjunctions. They also work well before narrative or opinion writing because students can apply the same words to connect reasons, events, and details in their own paragraphs.
Common errors to watch for
Some children use and for every connection, even when the ideas contrast. Others choose so without a cause-and-effect relationship. Watch for run-on sentences, missing commas in longer joined sentences, and sentences that do not make sense after the conjunction is added. Encourage students to reread the whole sentence aloud.
