In this set of PPT, topics of grammar structures are listed at the beginning of each lesson as “Objectives”. Each topic is linked to a few PPT slides for classroom practice. You can choose the ones you want to use in any order you like, or use all of them.
For most of the practice slides, the answers are provided after students answer them with just another click, so the structures are reinforced.
At the end of each set of practice, there is a button which can bring you back to the first page (objectives), where you can pick another topic.
