Built in a real classroom, not a content farm

I am Greg, and I have taught middle-school math for more than twenty-five years. In that time I have taught the same standards hundreds of times over — ratios in sixth grade, proportional reasoning in seventh, slope and linear functions in eighth — and watched class after class hit the same walls in the same places. Math Class 678 is everything I learned in those years, turned into the resource I always wished I could hand a new teacher down the hall.

The idea started the way most good classroom ideas do: out of frustration. I would find a reference chart I liked from one place, a practice worksheet from another, and a quiz from a third — and spend a prep period stitching three mismatched files into something coherent, only to do it again for the next skill the next week. So I built the thing I actually needed. One standard, one sheet, the whole lesson in one place.

I did not set out to make worksheets. I set out to stop reinventing the same lesson every Sunday night.

Why one sheet per skill

Middle-school math breaks down into discrete, teachable skills, and each Common Core standard deserves its own complete treatment. Bundle ten skills into a forty-page packet and the structure of the math disappears; the student cannot see where one idea ends and the next begins. Split a single skill across a reference sheet, a worksheet, and a separate quiz and you spend the period hunting through three files. The 4-in-1 format keeps the whole arc of a skill — see it, practice it, apply it, prove it — in one printable you can hand out in thirty seconds.

The mistakes are the part you cannot fake

Anyone can generate practice problems. What twenty-five years actually buys you is knowing exactly how a thirteen-year-old will get a problem wrong. When students distribute, a predictable share of them will multiply the first term and forget the second. When they write inequalities, they will reverse the symbol for "at least." Those specific, recurring errors are baked into every sheet as common-misconception callouts with redirect language ready to use — because the hardest part of teaching a skill is not explaining it right, it is catching it going wrong.

Designed to survive your copier

Every reproduction page is built against a restrained two-color system so each line stays legible after a pass through a tired school Xerox at 7:40 in the morning. The layouts assume the realities of the job: the sub day, the fire drill, the kid who was absent, the copier that only does black and white. These are not decorative documents. They are made to be used hard.

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, jump to your grade, or start with the free resources before spending a dollar.
