This week we learned what a TP, CM, CD and a CS.
A TP or the Topic Sentence is the sentence that says what the paragraph is about.
The CM or the commentary is almost like an opinion about what you are talking about.
A CD or a Concrete Detail is the sentence that has actual proof about the story you are talking about in the paragraph.
finally a CS or a Closing Sentence is the part of the paragraph that wraps up everything and closes the paragraph.
