Using Conjunctions: Because, But, So | Sentence Writing Activity

Help your students learn how to expand their ideas by connecting sentences with the conjunctions because, but, and so. This engaging writing activity encourages students to think about how the same sentence starter can be extended in different ways.

Students are given a sentence starter and are asked to complete it three different times using the conjunctions because, but, and so. This helps students understand how conjunctions change the meaning of a sentence by showing a reason, a contrast, or a result.

This activity builds strong foundations in sentence structure, grammar, and writing fluency, while encouraging students to think creatively about how ideas connect.

Students will practise:

• Using because to give a reason
• Using but to show a contrasting idea
• Using so to explain what happens as a result
• Expanding simple sentences into more detailed ideas
• Understanding how conjunctions change the meaning of a sentence

This resource is perfect for:

• Writing lessons
• Grammar mini-lessons
• Literacy rotations
• Small group work
• Independent writing practice
• Early finishers

Designed for early writers, this activity supports students in building stronger, more interesting sentences while developing confidence using common conjunctions in their writing.
