I absolutely love Orion abacus association! Their website, orionabacus.org, is easy to navigate and provides all the information one needs to get started with abacus training. The instructors are friendly and professional, making the learning experience enjoyable. I have seen significant improvement in my mental math skills since joining the courses. Highly recommended!
