Little Brother used these math books in fifth grade last year. They are long, narrow books. There are 40 pages in each book. The book on the far right is the answer booklet.

Do you recognize the character on the front of the textbooks? He is called Astro Boy outside of Japan. He is called Atomu in Japan. The girl is Uran.

The first page of each book is a table of contents. Here are the first pages of math problems in each textbook. Click to enlarge.

There is a certificate of completion at the end of each book. They did a lot of math worksheets, too. They call them purinto. It’s the English word “print” in Japanese pronounciation.

They studied fractions, decimals, and geometry, etc. in fifth grade.
