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.
Supplemental further 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 (the easiest) 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.

What began in 2004 as a couple of small help files illustrating some little known abacus techniques has since grown into a whopping 350+ mega bytes of
techniques &
tutorials. Putting these pages together has been a labor of love;
hand crafting each gif image, coding html, writing and rewriting so that
each segment reads well and its content is clear. Every
new addition has contributed to making these pages the best and most extensive resource for learning abacus anywhere.
But web hosting pages of this
magnitude comes with a cost. Please use all of the abacus tutorials and manuals
freely. Take from them what you will. If after working with the material you
feel you've come away with something worthwhile and would like to help with a
contribution it would be very
welcome. Just click on the Donate button above.
Every dollar counts and everything collected goes toward web hosting and helps to ensure that these pages remain online for everyone to use.
