Welcome to Grammaropolis.
A town with twenty-six characters who each ARE a part of speech or punctuation mark. They teach grammar by being it. Nelson runs the Noun Office. The Punctuation Department patrols the sentences. The Mayor presides over the lot of them.
"Welcome to Grammaropolis. Twenty-six characters. One town. Every kind of word filed somewhere."
"Yo. He didn't invite me."
Six verbs. One character. A whole town.
A kid meets Nelson at the Noun Office. They learn nouns with him, take his quiz, write a story with him, see him again in a music video, and come back the next year a grade older. The relationship deepens; the grammar follows.

Kids need the conventions of standard English that let them communicate clearly when it matters. Kids also need a voice: permission to use language as something theirs and not just something they perform on a worksheet. Grammaropolis was built so they could have both.
