This is a sheet that contains persuasive sentence starters. Cut the sentence starters our and give to children to use while writing their persuasive sentence, or paragraph, depending on the grade level. You could use these to show how persuasive writing differs from other types of writing, and the clues that we look for in writing to tell the type of text it is.
You already know you don't want to read a speech verbatim from a screen or notes. You could memorize the speech word-for-word, but not everyone is able to do that--and it isn't natural. Instead, use "key images" to remember your important points.
