Any way you say it, kids have a hard time writing it!
My students have difficulty distinguishing between the topic, or title, of a paragraph and a complete topic sentence. They often write phrases as the first sentence of their paragraphs because they don’t recognize the differences between the two.
This game is a sorting activity that gives your students practice in identifying topic phrases and topic sentences, so that they can remember to write a complete sentence each time they write a paragraph.
