MathKong is two things, kept on purpose separate: a free study site for Grades 7, 8 and 9 — and a small hand-drawn card game for math clubs and classrooms. This site is the study half. The card game lives on its own page.
If English isn't your first language — or if the teacher explains it once and moves on — the hardest part of math isn't the math. It's the wall of vocabulary between you and the idea.
By the time you've figured out what "factor" or "coefficient" means, the class is on the next step. You copy down the example and hope it clicks later. Sometimes it doesn't.
This site is a quiet place to catch up. Every topic is written by hand in friendly english, with worked examples, "friend notes," and quizzes you can take at your own pace. Free, no sign-in, no streaks.
Every lesson, every quiz, every card design passes these three checks before it leaves the desk.
If a sentence sounds like a textbook, rewrite it. The goal is always: could a friend say this out loud at a lunch table?
Every concept gets at least one example with the logic written out. No "left as an exercise for the reader."
Quick-check quizzes, a sparkly review-the-page nudge when you get one wrong, and two arcade games for between rounds. Practice that doesn't feel like punishment.
Right now Grades 7, 8 and 9 each have a full booklet plus a practice quiz set. The rough plan for the year:
