Teaching opinion writing in 3rd, 4th, and 5th grade can feel tricky because your students usually have plenty of opinions, but they do not always know how to support those opinions with clear reasons, examples, and explanations. They might say, “I think we should have extra recess,” but then struggle to explain why in a way that feels organized and convincing.
That is where picture books can make opinion writing feel more concrete.
When you use books for teaching opinion writing, your upper elementary students can see what strong opinions sound like before they begin writing their own. They can notice how characters state what they want, give reasons, respond to another point of view, and use voice to make their writing more interesting.
These books are great mentor texts for helping your 3rd, 4th, and 5th grade students practice opinion writing in a way that feels engaging, accessible, and easy to connect to their own writing.

Stella Writes an Opinion by Janiel Wagstaff
Stella Writes an Opinion is one of the most direct mentor texts for teaching opinion writing because it was written specifically to model the opinion writing process. Stella has an opinion that second graders should be able to bring a morning snack, but she quickly learns that stating her opinion is not enough. She needs reasons, support, and a closing that reminds readers why her opinion matters. This makes the book especially helpful when your students are learning the basic structure of opinion writing because they can see the process from idea to finished piece. It is also a good choice when you want a mentor text that closely matches the language of classroom writing instruction.
A simple classroom follow-up is to have your students choose a school-based opinion, such as whether students should have extra recess, snack time, flexible seating, or more choice in reading. Then they can practice stating their opinion clearly, adding reasons, and ending with a closing sentence that connects back to their opinion.
I Wanna Iguana by Karen Kaufman Orloff
I Wanna Iguana is a classic choice for teaching opinion writing because the whole story is built around a child trying to convince his mom to let him have an iguana. The letter format makes the opinion easy to identify, and the back-and-forth between Alex and his mom helps your students see that strong opinion writing often responds to another person’s concerns. Instead of simply saying, “I want an iguana,” Alex gives reasons, makes promises, and tries to show why his opinion makes sense. This is a great mentor text when your students are ready to move beyond basic reasons and begin thinking about counterarguments.
After reading, your students can write their own persuasive letters asking for something they want. They might write to a parent, teacher, principal, or even a fictional character. To make the writing stronger, you can ask them to include one possible concern the reader might have and then respond to it with a thoughtful reason.
I Want a Dog: My Opinion Essay by Darcy Pattison
I Want a Dog: My Opinion Essay is another helpful book because it connects directly to the kind of opinion writing students are often asked to do in school. In the story, cousins Dennis and Mellie think carefully about what kind of dog would be the best fit for their families. They compare different needs, preferences, and situations before Dennis writes an opinion essay for his teacher. This makes the book especially useful for showing your students that opinion writing is not just about what you want. It is also about using criteria, thinking through options, and explaining why one choice is better than another.
This book pairs well with a “best choice” opinion writing prompt. Your students could write about the best classroom pet, the best school lunch option, the best type of recess equipment, or the best book for a class read aloud. The key is to have them explain why their choice is the best fit, not just why they personally like it.
The Perfect Pet by Margie Palatini
The Perfect Pet by Margie Palatini is a fun book to pair with opinion writing because it gives your students a familiar and high-interest topic: choosing a pet. Pet-themed opinion writing usually works well in upper elementary because students tend to have strong feelings about animals, but the topic is still light enough to keep the lesson approachable. This book can help your students think about what makes a reason convincing. A student might want a pet because it is cute, but a stronger opinion piece will also explain why that pet would be practical, manageable, or a good fit for a family or classroom.
After reading, your students can write about the perfect pet for a classroom, a family, or a specific character. This is also a natural way to practice comparing options because students can explain why one pet would be a better choice than another.
A Pig Parade Is a Terrible Idea by Michael Ian Black
A Pig Parade Is a Terrible Idea is a strong opinion writing mentor text because the opinion is clear right from the title. The book gives one funny reason after another for why a pig parade would not work, which makes it easy for students to see how reasons can support an opinion. It is also a good mentor text for teaching elaboration because the reasons are not just listed quickly. They are developed with humor, examples, and specific details.
This book works well when your students need practice adding more detail to their reasons. After reading, they can write their own version with a new topic, such as “A Dinosaur Parade Is a Terrible Idea,” “A Cat Parade Is a Terrible Idea,” or “A Teacher Parade Is a Terrible Idea.” The silly structure makes the writing feel fun, but your students are still practicing a clear opinion, multiple reasons, and supporting details.
The Day the Crayons Quit by Drew Daywalt
The Day the Crayons Quit is a great book for teaching opinion writing because each crayon has a complaint, a point of view, and a reason for feeling the way it does. This book is especially helpful when you want your students to see that opinion writing can have voice. Each crayon sounds different, and each letter gives students a chance to notice how the writer’s personality comes through while still making a point.
This book is a great follow-up to more structured opinion writing lessons because it helps students add more expression to their writing. After reading, your students can write from the point of view of a classroom object, school supply, book character, or even a food item. The focus can be on stating an opinion clearly while using voice and examples to make the writing more engaging.
Can I Be Your Dog? by Troy Cummings
Can I Be Your Dog? is a sweet and funny book that works well for opinion writing because the dog, Arfy, is trying to convince someone to adopt him. The letter format gives your students a clear model for persuasive writing, but the real strength of this book is audience. Arfy writes to different people, and each letter gives your students a chance to think about how writers can adjust their reasons depending on who will read the piece.
This is a helpful mentor text when your students are ready to think beyond “What do I want?” and start asking, “What would convince my reader?” After reading, your students can write letters from the perspective of an animal, object, or character trying to be chosen. They can practice tailoring their reasons to a specific audience, which is an important part of strong opinion writing.
Hey, Little Ant by Phillip and Hannah Hoose
Hey, Little Ant is a great book for opinion writing because it naturally leads to debate. The story presents a kid deciding whether or not to squish an ant, while the ant gives reasons for why it should live. This makes it especially useful when you want your students to practice taking a side and supporting it with reasons.
This book also helps students think about perspective. Some students may begin with one opinion and change their minds after hearing the ant’s point of view. That makes it a strong mentor text for discussing how reasons can influence a reader. After reading, your students can write an opinion paragraph answering whether the kid should squish the ant, using reasons from the text and their own thinking.
Duck! Rabbit! by Amy Krouse Rosenthal
Duck! Rabbit! is simple, but it can be very effective for introducing claim and evidence. Two voices argue over whether the image is a duck or a rabbit, and each side uses visual details to support its opinion. Because the book is short and easy to understand, your students can focus on the structure of the argument without getting overwhelmed by a complicated plot.
This is a good book to use early in an opinion writing unit. Your students can practice making a claim and backing it up with evidence from the picture. You can also extend the lesson by showing an optical illusion or unusual image and asking students to write their own opinion paragraph about what they see.
Click, Clack, Moo: Cows That Type by Doreen Cronin
Click, Clack, Moo is a fun mentor text for opinion writing because the cows have a clear request, and they use written communication to try to get what they want. The story gives your students a chance to think about fairness, negotiation, and how writing can be used to solve a problem.
This book is especially useful when teaching persuasive requests. Your students can think about what the cows want, why they want it, and how Farmer Brown responds. After reading, students can write letters from the point of view of another farm animal asking for something they believe they deserve. This keeps the writing playful while still giving students practice with opinions, reasons, and persuasive language.
The True Story of the Three Little Pigs by Jon Scieszka
The True Story of the Three Little Pigs is a strong opinion writing mentor text for upper elementary because it helps students think about point of view and bias. In this version, the wolf tells his side of the story and tries to convince the reader that he has been misunderstood. This gives your students a chance to analyze whether his argument is actually convincing.
This book works well when your students are ready to think more critically about opinion writing. They can ask questions like: Do I believe the wolf? Which details support his side? Which details seem suspicious? After reading, students can write an opinion piece explaining whether they believe the wolf’s version of events.
Dear Mrs. LaRue by Mark Teague
Dear Mrs. LaRue is another strong mentor text for persuasive letter writing. Ike, the dog, writes dramatic letters to his owner while he is at obedience school. His letters are full of complaints, exaggeration, and attempts to persuade his owner that he has been treated unfairly.
This book is helpful because it gives your students a chance to talk about believable support. Ike has plenty of opinions, but not all of his reasons are equally convincing. That makes this a good book for helping students evaluate the strength of an argument. After reading, your students can decide whether Ike is convincing and then revise one of his complaints to make it stronger.
A Fine, Fine School by Sharon Creech
A Fine, Fine School is a good book for opinion writing because it connects to a topic your students can easily understand: school. In the story, the principal loves school so much that he keeps adding more school days. This creates a natural opportunity for students to form an opinion about whether more school is a good idea.
This book works especially well for 3rd, 4th, and 5th grade because students usually have plenty to say about school schedules, weekends, recess, and free time. After reading, your students can write about whether students should go to school on Saturdays, whether the school year should be longer, or whether kids need more time away from school.
Earrings! by Judith Viorst
Earrings! is a fun book for teaching opinion writing because the main character desperately wants pierced ears and gives many reasons to try to convince her parents. Some of her reasons are funny, dramatic, and not exactly strong, which makes the book useful for helping students evaluate what makes a reason convincing.
After reading, your students can look at a few of the character’s reasons and decide which ones are strong and which ones need more support. Then they can write their own opinion piece about something they want, focusing on reasons that would actually persuade the reader instead of simply repeating the opinion.
How to Use Books to Teach Opinion Writing
You do not need to use all of these books in one opinion writing unit. Instead, choose a few mentor texts that match the skills your students need most. If your students are just learning the structure of opinion writing, Stella Writes an Opinion or I Want a Dog: My Opinion Essay can give them a clear model. If they need help adding voice, The Day the Crayons Quit or Dear Mrs. LaRue can help. If they need to work on reasons and evidence, Duck! Rabbit!, A Pig Parade Is a Terrible Idea, or I Wanna Iguana are strong choices.
One simple way to use these books is to read the book aloud, identify the opinion, discuss the reasons, and then have students try the same skill in their own writing. This keeps the lesson focused and helps students transfer what they noticed in the book into their own opinion paragraphs, letters, or essays.
Ready for More Opinion Writing?
Teaching opinion writing is easier when your students can see what it looks like first. Picture books give your 3rd, 4th, and 5th grade students clear examples of opinions, reasons, persuasive language, point of view, and voice.

Strong opinion writing means choosing a clear opinion, supporting it with reasons, and explaining those reasons in a way that makes sense to the reader.
