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
• Texas Essential Knowledge and Skills for Mathematics: tea.texas.gov
• Texas Essential Knowledge and Skills for English Language Arts and Reading: tea.texas.gov
• Texas Essential Knowledge and Skills for Science: tea.texas.gov
• Texas Essential Knowledge and Skills for Social Studies: tea.texas.gov
• Florida B.E.S.T. Standards for Mathematics: cpalms.org
• Florida B.E.S.T. Standards for English Language Arts: cpalms.org
• Florida Next Generation Sunshine State Standards for Science: cpalms.org
• Florida Next Generation Sunshine State Standards for Social Studies: cpalms.org
• Virginia Standards of Learning for Mathematics: doe.virginia.gov
• Virginia Standards of Learning for English: doe.virginia.gov
• Virginia Standards of Learning for Science: doe.virginia.gov
• Virginia Standards of Learning for History and Social Science: doe.virginia.gov
• Georgia's K-12 Mathematics Standards: case.georgiastandards.org
• Georgia's K-12 English Language Arts Standards: case.georgiastandards.org
• Georgia Standards of Excellence for Science: case.georgiastandards.org
• Georgia Standards of Excellence for Social Studies: case.georgiastandards.org
• New York State Next Generation Mathematics Learning Standards: nysed.gov
• New York State Next Generation English Language Arts Learning Standards: nysed.gov
• New York State K–12 Social Studies Framework: nysed.gov

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 part that must be exact, the standard text itself, is verified against the official source rather than generated. The connections between standards are handled separately, as described below.

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 connections come from those documents.

Where it does not, which is most of Common Core Math, the connections are proposed, not taken from an official document: candidates come from the framework's own structure (the same topic in neighbouring grades) and from a model reading the standards. A second model then checks each candidate against the two standards' official text and rejects the ones that do not hold. Only connections that pass that check appear on a page, and the "essential" or "supporting" label is our rating, not the publisher's. A reviewed connection is a sound teaching sequence; it is not a citation of an official progression document.

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.
