How These Pages Are Made

The standard text quoted at the top of each page comes from the official framework publisher. Before a page is published, we verify that text against the current official source:

• Common Core State Standards for Mathematics: corestandards.org
• Common Core State Standards for English Language Arts: corestandards.org
• Next Generation Science Standards: nextgenscience.org

Each page footer shows the source we checked and the date we checked it. Pages that fail verification are not published.

The explanation and teaching ideas on each page are drafted with AI, working from the verified standard text, the grade level, and the surrounding cluster or topic. Drafts follow a strict editorial template: plain language, concrete classroom activities, and no filler. Every draft is checked automatically against those rules, and drafts that miss the bar are rewritten or dropped. We review samples from every batch before publishing.

We use AI here because it lets us cover thousands of standards with consistent structure and quality. The parts that must be exact, the standard text itself and the connections between standards, are verified against official sources rather than generated.

The "Before This Standard" and "What This Unlocks" sections come from a reviewed graph of prerequisite relationships. Where the framework publishes its own progressions, like NGSS articulation tables and the Common Core ELA reading threads, the edges come from those documents. Where it does not, we build candidate edges and verify each one before it appears on a page.

These pages are written and maintained by the team behind Lesson Maker Pro, a lesson planning tool for teachers. Standards alignment is the core of our product, so this catalog gets the same verification pipeline our lesson generator relies on.
