The claim, evidence, reasoning framework is a staple of middle and high school writing instruction, and Antuna's Story gives students plenty of material to practice with. The novel is short enough to reread key scenes, yet layered enough that students can defend different claims. Teachers who use it for CER paragraphs often find that students engage more because the insect characters feel approachable. The challenge is grading dozens of paragraphs without losing track of what each student has mastered.

Begin with a modeled paragraph. Present a claim such as "Antuna proves that cooperation matters more than strength," add evidence from a scene where small insects from different species solve a problem together, and then explain why that scene supports the claim. Label each part in different colors so students can see the structure. Ask them to identify which sentence is the reasoning, since that is usually the part they find hardest.

Next, let students practice with shorter claims before moving to full essays. A single paragraph with one claim and one piece of evidence is easier to score and easier to revise. Because the book has many strong scenes, you can assign different claims to different groups and compare results afterward. This keeps the activity fresh and discourages students from borrowing each other's work.

Scoring Each Part of the Framework

A three-part scoring sheet speeds up grading considerably. Give each of claim, evidence, and reasoning a score from zero to three, and add brief notes only where a student lost points. A paragraph with a strong claim and relevant evidence but weak reasoning will show that pattern immediately. Over several assignments, you can see which component each student needs to work on.

• Claim is specific, arguable, and answers the prompt directly
• Evidence is accurate, relevant, and taken from a real moment in the text
• Reasoning explains the link between the evidence and the claim in the student's own words
• Quotations or paraphrases are introduced smoothly and cited correctly
• The paragraph stays focused on one main idea from start to finish

Fixing Weak Reasoning

Weak reasoning usually takes one of two forms. Either the student repeats the evidence in different words, or the student jumps to a big conclusion without showing the steps. A useful revision prompt is "so what?" because it forces the student to explain why the evidence matters. Writing that question beside the paragraph is often enough to trigger a better second draft.

Sentence starters can help students who stall, such as "This shows that" or "This matters because." Use them as temporary supports and gradually remove them as students gain confidence. Be careful not to accept sentence starters followed by empty statements. A reasoning sentence should still add something the evidence alone did not say.

Handling the Grading Load

CER assignments multiply quickly, especially when you assign several per unit. To keep the workload sustainable, consider scoring most paragraphs with the three-part sheet and reserving detailed comments for one paragraph per student each cycle. AI feedback tools can draft the three-part scores and short comments, which you then review. This combination keeps feedback frequent without consuming every evening.

Track results in a simple spreadsheet so you can spot class-wide trends. If most students lose points on reasoning, plan a mini-lesson using anonymous examples from their own work. If evidence selection is the problem, spend a day practicing how to choose the most relevant scene. Data from CER paragraphs on Antuna's Story can then guide instruction for the rest of the school year.
