The Bead Unbaffled - An Abacus Manual
Rather than learn online, many prefer to work using printed material. Given the large number of images in the manuals and tutorials, these Adobe Acrobat (.pdf) files offer the best solution for printing. There are two options. The first is the manual as it appears on the internet and all supplemental examples may be printed separately. The second manual includes all the supplemental material. Essentially it's all the files rolled into one.

Takashi Kojima's Abacus Examination Examples

In Japan the Abacus Committee of the Japan Chamber of Commerce and Industry would hold examinations for individuals wishing to obtain a license to work as an abacus operator. The examinations began at the tenth grade level (least difficult) and worked up to the first grade level (most difficult). Those individuals who passed first, second or third grade examinations qualified for employment in government or business concerns. The examples in the file below come from Takashi Kojima's book entitled, The Japanese Abacus, It's Use and Theory. The examples illustrate sixth grade through third grade questions.
   ▪ Examination Examples (9 pages, 84 kb pdf)
Web hosting pages of this magnitude comes with a cost.

Please remember these pages in your prayers :)
