Students correct three weak topic sentences — a vague dog sentence, a filler volcano opener, and a non-specific ocean description. Part B has four fill-in-the-blank questions about what a topic sentence does, how facts support the main idea, and the term for connector words. Part C has two short-answer questions about why strong topic sentences matter and what types of details support them.
Revising weak topic sentences gives students immediate practice with the most important sentence in every informational paragraph.
