**EDIT**
Here is my PPT with two lessons worth plus a document containing a lesson plan for each lesson in the PPT.
It is an update and improvement on last year's PPT.
Some of the content is borrowed from others on this thread.
I used Tom_Waygook's worksheet above in my lesson, so I won't repost it.
I have also attached a list of set "as (adjective) as" comparisons that you might find useful.
Hope it helps!
