がっこま: Middle-School Math in Manga and Quizzes
A free Japanese-language demo that teaches first-year middle-school positive and negative numbers through a short manga followed by a quiz.
- For
- Japanese middle-school students starting signed numbers
- Worth noticing
- The sample pairs a six-page manga with a five-question quiz that gives immediate correctness feedback and a short explanation.
Field notes
The sample opens with a six-page manga episode set in Numeland, where the younger fairy Mainassu disappears; the math topic is positive and negative numbers. A five-question multiple-choice quiz follows, with immediate correctness feedback and a short explanation, and the page shows a completed 5/5 result. The site says it is releasing one unit at a time, with a monthly target; the remaining middle-school chapters appear as a roadmap rather than available lessons.
