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.
Abacus Exercise Sheets
All of the
following exercise sheets are in Adobe Acrobat (.pdf) format. Each of the
files is about 24 kb in size and contains
three pages
of exercises. Each section offers two printing options; either with or without the
answers included on the page.

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.
