At the end of Chris Van Allsburg's book, the boy's sister Sarah hears the bell ring while their parents hear nothing at all. That moment gives teachers a rich opinion-writing prompt because students can reasonably disagree about what it means. Asking whether the bell is real, or whether believing is what makes it ring, produces claims that are arguable without being tied to a single correct answer.

The grading challenge is that students may take positions you personally disagree with, and a fair score has to ignore that completely. The rubric should reward whether the writer states a clear position, supports it with reasons drawn from the story, and ends with a conclusion that connects back to the claim. A student who argues the bell is simply magic can earn the same score as one who argues it represents belief, provided each supports the claim well.

Teachers can protect this fairness by writing the criteria in terms of reasoning rather than conclusions. Statements such as "gives at least two reasons" and "uses a detail from the text to support each reason" can be checked without any reference to which side the student chose. This also teaches students that strong arguments are built, not guessed, which is a lesson that carries into later grades.

What Counts as Evidence From a Picture Book

Picture books offer two kinds of evidence, the words and the illustrations, and students should be taught that both count. A child might point out that the boy listens carefully to the sound of the bell while the other characters seem not to notice, or that the final scene shows an ordinary living room with a quiet moment of wonder. Evidence from art is legitimate when the writer explains what the picture shows and why it supports the claim.

• Claim: the writer states clearly whether the bell is real, magical, or a symbol of belief.
• Reason one: a first supporting point that is connected directly to the claim.
• Reason two: a second, different supporting point rather than a repeat of the first.
• Text or picture evidence: a specific moment from the book that backs up each reason.
• Closing statement: a final sentence that restates the opinion in a fresh way.

Common Weaknesses in Early Opinion Essays

Young writers often state an opinion and then simply repeat it with different words, such as saying the bell is real because it is real. Others retell the plot at length without ever returning to their claim, leaving the reader to guess the point. Naming these patterns in advance helps teachers write comments that are specific, like "You told me what happened, now tell me why it proves your idea."

Another frequent issue is the lack of a counterargument, which upper elementary and middle school students are ready to try. Asking them to explain why someone might disagree, and why they still hold their view, raises the level of thinking considerably. A single sentence beginning with "Some people might say" is often enough to move a paper up a rubric level.

Scoring Large Sets Without Bias

When dozens of essays argue the same two or three positions, the real risk is letting your reaction to the position leak into the score. Reading for structure first, and ignoring the stance until the end, helps keep that influence in check. Some teachers cover the conclusion on a first pass so they judge the reasons on their strength alone.

AI grading tools can support this discipline because they apply the written criteria without any opinion about the topic. GraideMind, for instance, scores against the rubric a teacher defines, so a student arguing for belief and a student arguing for pure fantasy are measured by the same standard. The teacher can then spot-check results and adjust, keeping judgment where it belongs.

Extending the Assignment Beyond the Holiday

The opinion structure practiced here transfers easily to other books and subjects. Once students know how to name a claim, give two reasons, and support each with evidence, the same frame works for science explanations and social studies arguments. Teachers who teach it with a warm, low-stakes story often find students more willing to take risks with their thinking.

Saving a few strong examples from this unit gives you models for the rest of the year. A paper that argues clearly with two reasons becomes a reference point when students struggle with a similar task in March. Building that shared library of good work is one of the quiet benefits of choosing a prompt students care about.
