Writing is more than just a way to show what we know—it’s a tool for thinking, processing, and discovering. One of the most effective and versatile strategies for strengthening student voice and supporting content-area learning is the Claim, Evidence, Reason (CER) paragraph. This structure helps students organize their thoughts and communicate their ideas, whether they’re in an English, science, or social studies classroom. The CER paragraph is a strong place to start if your team or school wants to build consistency in writing expectations. In this post, you’ll find ideas for teaching CER using the mentor text The One Thing You’d Save by Linda Sue Park and Robert Sae-Heng, along with practical tips for helping students develop strong, thoughtful responses.

After doing some reflection over break, I got to thinking...how can my students remember the setup for the claim and the punctuation? CLAIM-TERPILLARS OF COURSE!
