Sentence Demarcation — Interactive Lesson (KS1)

Does every sentence start with a capital letter? This 25-slide interactive lesson teaches sentence demarcation, the punctuation that shows where a sentence begins and ends.

Mastering Sentence Demarcation in KS1 English

Children learn to understand what a sentence is and why it needs demarcation, and to use capital letters to start sentences and for proper nouns. They practise finding the capital letter in a sentence, then learn the three main end punctuation marks: full stops to end statement sentences, question marks for questions and exclamation marks for exclamations. True-or-false questions check whether a sentence is correctly demarcated.
