In this lesson, pupils recap how simple sentences are structured and learn how to use them impactfully in writing. Through clear modelling and purposeful examples, children explore how a simple sentence communicates one key idea using a single clause. They learn when simple sentences create clarity, when they add impact, and when longer, multi-clause sentences are more useful. The lesson guides pupils to identify, construct and apply simple sentences with control, before using them deliberately in their own writing. Differentiated tasks support all learners in building confidence and using simple sentences for purpose and effect.
