Sai Speed Math Academy Abacus Mind Level 1 Workbook 2 of 2: Excel at with Soroban, a Japanese

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.

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