Here are two lessons [roughly 30 minutes each] which I have used with my Year 6 children to recap and condense their knowledge on statements, commands, exclamations and questions. There is a detailed powerpoint, which leads children through each of the definitions and provides them with plenty of modelling so they are familiar with each of the concepts. There are also several opportunities throughout the powerpoint for them to have a go at writing their sentences. For the first lesson, children identify the type of sentence and what punctuation suits it the best. I have rewritten SATs style questions for this activity. For the second lesson, children change the types of sentence and one again I have rewritten SATs style questions.
