From the bank — system of equations

In the system x + 2y = 6, 2x + 3y = 4, someone misread the 4 and solved to get x = −2. Find the value that 4 was mistakenly read as.

Problems an algorithm can’t write.

A generator varies the numbers. It cannot decide that someone misread one. Every problem here was written by a person, taught in a classroom, and checked by hand — over twenty years.

From Gripul Math, a mathematics practice teaching the Korean curriculum since 2002 — gripulmath.com. The bank is the same one our own instructors teach from.

Compare

The same topic, two different questions

Both sets below are real. The left column is what a parameterized generator produces for “systems of equations” and “factoring.” The right column is what sits in our bank under the same standards.

Generated

Numbers vary. The question doesn’t.

  1. 1
    y = 6x − 11
    −2x − 3y = −7
  2. 2
    2x − 3y = −1
    y = x − 1
  3. 3
    b² + 8b + 7
  4. 4
    n² − n − 56

Written

Each one asks something new.

  1. 1
    Let a be a root of x² + x − 7 = 0. Find the value of a² + a − 5.
  2. 2
    Factor (x+1)(x+2)(x+3)(x+4) + 1.
  3. 3
    Given a+b+c = 4, a²+b²+c² = 10, a³+b³+c³ = 34, find abc.
  4. 4
    The graphs of 3x − y = 10 and ax + 4y = −4b meet at infinitely many points. Find b − a.

We keep the drill too — a worksheet needs both. What we have that a generator doesn’t is the second kind.

Every problem carries its Common Core code, so you can pull exactly the standards you are teaching this week — and see how many questions stand behind each one before you print.

Making one

Three steps, then paper

  1. Pick the topic.

    Browse the Common Core domains and check the standards you want. Each one shows how many questions the bank holds.

  2. Set the length.

    Up to 50 problems. Answer key generated with it, on its own page.

  3. Print it.

    Two-column layout, sized for one sheet. Diagrams included — no missing figures, no broken symbols.

Plainly

What this doesn’t do

  • No AI writes the problems.Not one. Current models get roughly one arithmetic question in twenty wrong, and more than that on multi-step word problems. That’s a wrong answer on a page you hand to 150 students.
  • No student accounts, no student data.Teachers only. Nothing to sign your class up for, nothing about them for us to hold.
  • Not unlimited.The bank is finite and we’ll tell you its size. A tool that claims infinite problems is generating them.
  • Not a curriculum.It makes worksheets. Your lesson is yours.
