No more boring calculations! Build your basic math skills with one page a day!

80% of elementary math is operations.
Since computation involves repetitive calculations, it can be quite tedious.
If the learning material is too much and boring, students will have a hard time studying.
“One Sheet a Day” is a fun and stress-free way to study by just taking one sheet a day.
Since you only need to solve one page per day, you can develop self-directed learning skills.
“One Page a Day” helps you understand the principles of calculations through friendly explanations of concepts and build a solid foundation in calculations through repeated learning.
Plus, you can enhance your mathematical creativity with a fun arithmetic playground on every fourth page.

We've carefully covered the necessary calculations for each unit!

“One Page a Day” is a textbook-linked calculation workbook that is tailored to the progress of school classes, allowing students to learn basic calculations, the foundation of elementary mathematics, efficiently in a short period of time.
We have meticulously covered the operations required in the areas of numbers and operations, as well as shapes and measurements, so that learning operations can be done in parallel with studying school mathematics.
Additionally, you can develop mathematical thinking skills and problem-solving abilities through word problems tailored to textbook topics.
You can systematically learn the entire calculations for a semester with just one book, “One Page a Day.”
