These are posters that display 4 of the most popular types of leads:
Asking a Question
Creating a Visual Image
Using the Phrase "Imagine that ..."
Examples of each lead are included on each poster
In addition, there is one poster that simply lists them all.
I initially show them on my Smart board, as I teach my Persuasive Opinion Unit (listed here on TPT), then post them to refer to all year.
My Persuasive - Opinion Writing Unit is the Cadillac of all writing units, with fully scripted lesson plans for a full month, tons of supporting documents several additional chart/posters, and so much more.
