Slideshow has questions for practicing "-er than," "the ---est," as well as "more than" and "most." More than and most is the second half in case it's split into multiple lessons. At the end of each section is a discussion question so the students can practice using the grammar in context. This goes with the New Horizons 2 textbook, Unit 6 pages 85-86. Hope it helps!
Here's the link to the google slides, let me know if anyone has any issues with it: https://docs.google.com/presentation/d/117jAC6aHn9U1HGsS2TeFBQNWPZk4gEzcOgw1mU-fNCs/edit?usp=sharing
Also attaching a PDF version so you can get an idea what it looks like even if the animations for the answers won't work
