How Sourdough Bread Rises
A loaf of sourdough bread starts as a flat, wet paste of flour and water. Hours later it has puffed up into a tall, airy loaf full of holes. No one pumped air into it. The bread was lifted from the inside by living things…

What's on each sheet
- Reading passage. Read the passage, then circle the letter of the best answer. Each question asks why the author wrote it and how you can tell. One fresh passage per sheet, with its own question set.
Every version prints on US Letter or A4, with its answer key on the last page.
How to teach this
Push from naming the purpose to proving it. When your child says "persuade," ask which sentence gives it away, usually one with "should" or "we must." When they say "inform," have them point to a fact that has no side. The skill at this level is matching the purpose to the evidence.
Watch for: A passage can be interesting and still be meant to inform, not entertain. Look for facts versus a made-up story. Persuading is not the same as informing. A persuasive writer wants you to agree or act, and usually says 'should' or 'we must'. The purpose is why the author wrote it, not what the passage is about. Two passages on the same topic can have different purposes.
Common questions about author's purpose
- How do I help my child prove the author's purpose?
- After they name the purpose, ask for the sentence that shows it. A persuasive passage usually has a line like "we should," an informational one has a plain fact with no side, and an entertaining one has a detail added just for fun. Purpose plus evidence is the goal.
- Why does the same topic have different purposes?
- Because purpose is why the author wrote, not what they wrote about. One writer might inform you how libraries work while another argues that your library should stay open on Sundays. Same topic, different reasons, and the reader's job is to tell them apart.
