Built in a real classroom, not a content farm

I am Greg, and I have spent more than twenty-five years teaching middle-school math. Math Class 678 is the resource I always wished I could hand a new teacher down the hall: one skill, one sheet, one complete lesson.

Every 4-in-1 Skill Sheet moves a student through four phases on a single printable artifact. A Reference page they keep. Practice that scaffolds from guided notes to sixteen sequenced problems. Apply problems that put the skill in a real context. And an Assess exit ticket with a clean answer key for you.

Why one sheet per skill

Middle-school math breaks down into discrete, teachable skills, and each Common Core standard deserves its own complete treatment. Bundling ten skills into one packet hides the structure. Splitting one skill across a reference sheet, a worksheet, and a separate quiz means hunting through three files. The 4-in-1 format keeps the whole lesson in your hand.

Designed to survive your copier

Reproduction pages are built against a two-gold color system so every line stays legible after a pass through a tired school Xerox. The common-misconception callouts are not generic — they are the specific errors each skill produces in real classrooms, with redirect language ready to use.

How the catalog works

This site is a showcase and a directory. It sells nothing on its own — every sheet lives on Teachers Pay Teachers, and every button here routes you straight to the listing. Browse the full catalog, or start with the two free sheets.
