"Abaku turns math into a game – joy is not a reward here, but a path to understanding."

Mathematics can be a source of frustration, or a source of joy. The difference is in the method. Abaku shows that joy is not a side effect, but a tool for learning. Children learn faster because they want to – not because they have to.

Every teacher faces a choice: either let children experience arithmetic as they have come to know it from experience – with the inevitable division into "those who progress" and "those who fall behind", or give them a chance to experience it as a game that pulls everyone forward.

And what could a teacher want for themselves and their students more than the joy of learning that brings real progress? Perhaps only support from excellent methodology that we offer you here – practical, simple and shared in school practice.

With wishes that it serves you well,

7 principles of the abacus example / number or "...what is abaku?"

The Abaku methodology consists mostly of 5/10/15-minute tasks, games, exercises and assignments, which we recommend using in your lessons at the beginning or end of the class. Its mission is to review, practice and strengthen the development of the ability to calculate mentally (up to 10, up to 100 and more). You can use the methodology in kindergartens, primary and secondary schools. All worksheets and crosswords can be printed and laminated for repeated use.
