There were no slides for lessons 3, 5, or 7, since the class time during these were spent doing exercises and no new grammatical material was presented. This will be the normal pattern for the classes.
Essentially I cannot find the ppt slides you have for Lesson 3 grammar.
Class 5 - was completion of Lesson 2 exercises. You shared the trilinear answers in the Class 5 post.
Class 6 (this post) - was Lesson 3 grammar (and a first few exercises). You had a presentation. I could not find the slides in this post (or any other post).
Class 7 - we completed Lesson 3 exercises. You shared the trilinear answers in the Class 7 post.
Hope this clarifies and hope I am not missing anything.
Thank you very much for pointing this out, Aparna. It looks as if I may have omitted to put those up online previously. I’m glad somebody is paying attention!
