Body abacus, particularly the hands, can be used to easily solve Table 9. This will hands with palms up and fingers will number, starting from the left thumb each finger with a digit from 1 to 10 . Whenever X multiply 9, corresponding to the digit down the X finger, and as a result the number of fingers positioned to the left of the finger will have down tens, while the number of fingers to the right of the corresponding finger X to be the units digit.

Thanks a lot! I haven't heard of the old abacus for a very long time. I remember I used it as a pupil and thanks to it I learned multiplication and addition. I found it very useful and friendly. And not only me! My generation. It taught us abstract things in a very concrete way. we shouldn't abandon old techniques that worked just because they are old!

Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
