Just got it and looks good, with very well explanations and steps to follow.

Five weeks ago before we started this, my seven year old daughter struggled to remember what 4+1 is. Now, into week five of the course, she can work out double figure sums in her head. Soroban is the reason Japan has the best child numeracy stats.

Výborné

I bought these for my son to work on his mental math skills with. They arrived quickly and they look amazing. I am really excited to get started. The lessons are designed to acclimate the learner and get them used to doing speed math. They start off very slowly so that the concepts can easily be grasped before moving up to more complicated material.
