Class 4 grammar worksheets for recognising, punctuating, and writing sentences with introductory clauses.
Practice that builds confidence
What Children Practise
These Class 4 grammar and writing worksheets help children understand how an introductory clause or opening group of words prepares the reader for the main idea of a sentence. Children practise reading the beginning carefully before completing or punctuating the sentence.
The printable activities include identifying introductory clauses, adding commas where needed, joining sentence parts, and writing original sentences. The work supports clearer sentence structure and more varied writing.
Introductory clauses and opening phrases give extra information before the main part of a sentence. In Class 4, children learn that an opening such as After the rain stopped, or While the class waited, should connect smoothly to a complete idea. These worksheets build the habit of asking, “What is the sentence mainly saying?”

Sentence Sense And Punctuation
The main skill is not only placing a comma. Children need to hear the pause after the introduction and then check that the rest of the sentence makes sense. For example, After lunch, the pupils returned to class. The opening tells when; the main clause tells who did what. Activities encourage children to separate the introduction from the main clause without breaking the sentence.
Parent Practice Routine
At home, read one sentence aloud without the comma, then again with a small pause after the introductory words. Ask your child which version is clearer. Next, let the child underline the opening part, circle the subject of the main clause, and add the comma. Finish by asking the child to write one sentence beginning with before, after, when, or while.

Classroom Uses
Teachers can use these pages during sentence lessons, writing workshops, editing practice, or morning grammar review. They are especially useful before narrative writing because children can vary sentence beginnings to show time, setting, or condition. Pair work also works well: one pupil reads, the other decides where the main clause begins.

Common Errors
Children may put a comma after the first word only, leave out the comma completely, or write an introductory clause without a complete main clause. Some may confuse a long subject with an introductory clause. Ask them to find the action and who or what is doing it in the main part of the sentence.
