How do I make a CER organizer?

Type the question or topic students are answering into the prompt box, add the subject and grade level, choose a style, then click Generate. Figviz produces a print-ready organizer with labeled Claim, Evidence, and Reasoning boxes. Refine the description and regenerate as many times as you like until it fits your lesson.

Can I get a blank CER worksheet or template?

Yes. Describe a blank layout, for example "a blank CER template with empty Claim, Evidence, and Reasoning boxes and writing lines." Figviz draws the organizer with empty boxes you can print and fill in by hand, or annotate digitally in any PDF editor. Blank templates are ideal for building a CER response together with your class.

What goes in each part, and how is reasoning different from evidence?

The claim is a sentence that answers the question. The evidence is the specific data, facts, or observations that back up the claim. The reasoning is different from evidence because it explains why that evidence proves the claim, using scientific principles or logic. Evidence is the what, and reasoning is the why that connects the evidence to the claim.

Is the claim evidence reasoning generator free?

Yes. Every Figviz account starts with free credits you can use right away, no credit card required. Buying a pay-as-you-go credit pack removes the watermark and unlocks 4K export resolution for large worksheet or poster printing. Credits never expire.

Can I use CER organizers in both science and ELA?

Yes. CER started in science for explaining lab results, but it works just as well in ELA for building text-based arguments. Use it for lab conclusions, reading responses, current events, and essay planning. Print copies for small groups, project one for a whole-class think-aloud, or assign the digital PNG through your learning management system.

What is claim evidence reasoning (CER)?

Claim evidence reasoning, often shortened to CER, is a three-part framework that helps students write a clear, well-supported response to a question. It is used across science and English language arts to build argument writing skills. A CER response has three parts: a claim that answers the question, evidence that supports the claim with data or facts, and reasoning that explains how the evidence connects back to the claim using scientific principles or logic. A CER graphic organizer lays out these three parts in labeled boxes so students can plan their thinking before they write. Figviz turns any question or topic into a finished CER organizer in seconds, so you can skip the drawing and focus on the writing.

The three parts of a CER response

Claim: a clear statement that directly answers the question or solves the problem. A strong claim is a single sentence that takes a position, for example "The sugar dissolved faster in hot water."

Evidence: the data, facts, or observations that support the claim. Evidence should be specific and measurable, such as numbers from an experiment, a quotation from a text, or a recorded observation.

Reasoning: the explanation that ties the evidence back to the claim. Reasoning answers "why does this evidence prove my claim?" by using scientific principles, rules, or logical connections that the reader may not already know.

A claim evidence reasoning example

Imagine a science question: "Does temperature affect how fast sugar dissolves?" A student runs an experiment and writes a CER response. Claim: "Sugar dissolves faster in warmer water." Evidence: "In the experiment, sugar fully dissolved in 30 seconds in water at 60 degrees Celsius, but took 90 seconds in water at 20 degrees Celsius." Reasoning: "Warmer water has more thermal energy, so its molecules move faster and collide with the sugar more often, which breaks the sugar apart more quickly." The claim answers the question, the evidence gives measured data, and the reasoning uses a scientific principle to explain why the evidence supports the claim. That is a complete CER.

CER sentence starters for each part

Claim starters: "My claim is...", "The data shows that...", "I found that...", "The answer to the question is..."

Evidence starters: "The evidence for this is...", "According to my data...", "In the text it states...", "During the experiment I observed..."

Reasoning starters: "This evidence supports my claim because...", "This happens because...", "The scientific principle behind this is...", "This shows that... because..."

Encourage students to use transition words like "because", "therefore", and "as a result" in the reasoning section to make the logic clear.

How to make a CER organizer with Figviz

Enter your question or topic: type the prompt students are answering, for example "Does temperature affect how fast sugar dissolves?" or "Was the narrator a reliable character?"

Add detail: mention the subject, science or ELA, the grade level, and whether you want sentence starters printed inside the boxes.

Pick a style: Classic keeps things simple, Colorful uses bright color-coded boxes that catch students' eyes, and Minimal works well for clean digital worksheets.

Choose what to include: ask for a blank template to fill in, a color coded version, or a worked example with sample answers.

Generate and refine: click Generate CER Organizer, then adjust your description and regenerate until the Claim, Evidence, and Reasoning boxes match your lesson.

Download and print: export at 4K resolution for a crisp worksheet or poster, or save the PNG for digital assignments.

Frequently asked questions

Claim evidence reasoning, or CER, is a three-part framework for writing a supported response. The claim answers the question, the evidence supports it with data or facts, and the reasoning explains how the evidence proves the claim using scientific principles or logic. It is widely used in science and ELA to teach argument writing.
