Grammar through character, since 2010.

The origin.

In December 2005, Coert was teaching seventh-grade writing at Pinewood School. The unit on parts of speech kept failing. The students were bright. The lessons were structured. The textbook covered the material. None of it stuck.

Coert gave the class a writing assignment: pick a part of speech, give it a personality, write a children's book about it. Their job was to teach the part of speech through the character. The students turned in stories about Nelson the Noun running a bureaucracy. Vinny the Verb saving the day. Jake the Adjective describing everything in sight. The pedagogy that hadn't stuck as a lesson stuck instantly as a story.

That assignment became the canonical Grammaropolis storybook line (eight picture books), the YouTube animated music videos (10M+ views), the subscription app, the workbooks you are looking at now, and the next-generation AI experiences at play.grammaropolis.com. The original insight is still doing all the work: characters ARE grammar, not metaphors for it. Nelson's bureaucratic personality IS what nouns do. Jake's compulsion to describe IS adjective-noun modification.

The catalog today.

Twenty-one books live today, plus the build path: thirteen workbooks (Grades 1-8 across the active departments) and the original eight-book Meet the Parts of Speech storybook line. At full coverage, the workbook side spans 40 single-grade SKUs (eight grades, five departments), pedagogically sequenced from word-level grammar through paragraph-level composition with vocabulary as a parallel skill. The storybook line is already complete at eight books (one per part of speech) and stays in print as the foundational IP the rest of the catalog grew out of.

The workbooks are written by The Mayor of Grammaropolis, with guest experts from the cast appearing department by department. The storybooks are illustrated by Powerhouse Animation and have been in print since 2010. Aligned to four state and national standards frameworks (Common Core, TEKS, Florida B.E.S.T., New York Next Generation). Printed via Lightning Source / Ingram and distributed through both direct-to-consumer (this site) and major retail channels (Amazon, Walmart, Bookshop, Barnes & Noble, school distributors). Coert Voorhees is the founder of Grammaropolis and the creator of the character cast; the Mayor speaks for the catalog.

What's special about it.

Five things you will not find in any other Grades 1-8 ELA workbook catalog:

1. Characters that are grammar. The pedagogy is encoded in the personality.
2. Standards alignment you can search. 1,166 standards, 4,900 page-level citations, four frameworks, one tool.
3. Samples without a form. Every workbook has a free six-page sampler. No email required.
4. Direct from the publisher. Bundles, signed editions, classroom-set kits ship from us, not from a third-party distributor.
5. An author whose IP grew out of his classroom. Coert taught seventh-grade writing at Pinewood from 2001 to 2006. The character cast came out of one of his student writing assignments.

The cast.

26 fully realized characters across the catalog. Nine parts of speech (Nelson, Vinny, Lucy, Jake, Benny, Roger, Connie, Pete, Izzy). Twelve punctuation marks (the Grammaropolis P.D.). The Mayor. Doctor Noize. Gabby Verbose. Plus supporting cast.

Each character has a fully specified voice in our character database, with signature phrases, teaching domains, and relationships to every other character. The book copy comes out of those character voices, not out of a generic marketing voice.

Where this is going.

The Parts of Speech department completes Grades 1-8 (Grades 6-8 in build). Punctuation single-grade conversion follows. The Writing Company Grade 5 pilot ships next, then the remaining grade volumes. Wonderful Words now has its sub-brand visual mark. Grammaropolis Mischief (activity books, joke books, sticker stories) launches as a sixth department in 2027.

The catalog architecture is designed to scale from 13 SKUs to 40 SKUs to 60+ without rebuilding. Every new book is a new content entry, not a new product line. Every department is a sub-brand world.

Built in Houston.

Grammaropolis is independent. The catalog is published from a small studio in Houston, Texas. Coert is the founder, the author of record, and the person you will reach if you email the company. The character art was originally produced by Powerhouse Animation. The editorial relationship is with Christopher Knight.
