Grammaropolis P.D.
To correct and serve.
Officer Period closes sentences. Chief Comma directs traffic. Sergeant Exclamation Mark gets a little too excited. Detective Question Mark asks the questions nobody else thought to. Apostrophe handles possession claims. Quotation Marks file the official transcript.
Twelve punctuation marks, all personified as members of the Grammaropolis Police Department. The pedagogy is in the casework: every comma rule is a procedure, every apostrophe error is a citation. Currently one combined Grades 3-5 volume in market; eight single-grade volumes in build per the 2026 Catalog Architecture brief.
The Department.
Twelve officers and specialists. Each one runs their corner of the punctuation beat.
What's available right now.
The combined Grades 3-5 volume is the current SKU. Eight single-grade SKUs (Grades 1-8) are in build per the 2026 Catalog Architecture brief; the combined volume retires when the single-grade versions ship.
Coming next: the single-grade split.
The Catalog Architecture build sequence calls for splitting the combined Grades 3-5 volume into eight single-grade SKUs (Grades 1 through 8), matching the industry convention every other elementary and middle-school ELA workbook publisher uses. Same characters. Same chapter spine. Grade-appropriate depth at each grade.
