This resource addresses the Grade 5 requirements to 'form and use perfect' form of verbs and to 'use verb tense to convey various times, sequences,states,and conditions'. It is a challenging unit of work, and would be equally appropriate for grades beyond grade 5. Originally, it was written as a single lesson, but given the scope of the vocabulary and concepts covered, It is probably better to extend it over two sessions.
The colorful presentation has teacher-operated conceal/reveal animation, and ends with a paired pupil exercise to be completed in the first lesson and reviewed in the second one. There is a KWL (know/wonder/learnt) chart to encourage self-assessment by pupils and give teachers insight into achievements and difficulties. The unit ends with a pupil worksheet at two levels to allow for differentiation. Weaker pupils can be set just exercise A, where the auxiliary verb and past participle appear consecutively in the sentences, and more able ones can be set the additional challenge of exercise B, where the auxiliary and past participle are split by other elements (eg adverbs, negatives) in almost all sentences.
Two of the slides have been saved in png format so that they can be printed out for classroom display.
