Join Them Up! Writing Compound Sentences

Student Task

• Write two short sentences: I like apples. I like bananas. Ask how to join them into one sentence.
• Teach the four joining words and the comma rule, then do activities 1 and 2 together.
• Students complete activities 3 to 6. Answers are in the answer key.

Classroom Use

• Sentence glue: students hold two sentence strips and a joining word card, then stand together to read the compound sentence aloud.
• Meaning match: the teacher reads a sentence half; students choose the joining word that makes sense with their arms (and = cross, but = push, or = point both ways, so = arrow forward).
• Choppy to smooth: pairs rewrite a choppy paragraph using two compound sentences.

Differentiation

Support: give a joining word chart with a meaning clue for each (and = add, but = different, or = choice, so = result). Challenge: add yet and for, and write a short paragraph mixing simple and compound sentences.

Answer Key & Assessment

Activities 1 to 5 check identifying and building compound sentences (answer key included). Activity 6 checks improving a paragraph.

Learning Objectives

• Explain that a compound sentence joins two complete sentences.
• Choose and, but, or or so to match the meaning.
• Write compound sentences with a comma before the joining word.

Teacher Tips

Remind students to check both halves: if each side can stand alone as a sentence, it is a compound sentence and needs a comma before the joining word. Too many joins make one long, confusing sentence, so one joining word per sentence is enough.
