Hello professor, I have a few questions to ask you before the final deadline.

1. I received three examples of the final assignment from massenger, which format should I refer to?
I'm confused each format is different.

2. You said not to introduce new vocabulary and structures in aims of lesson plan, but the samples included them.
Would it be okay to give a brief introduction?

3. Here are three kinds of topic I have in mind for beginner level students.
1) Last Weekend (past tense, past continuous...) 
2) New experience (perfect present...) 
3) How many or much...(count or uncountable nouns) 
Which title seems to be great to make a lesson plan?
