The famous ones are Pachi Pachi Land (Patchi Training) and Chibikko Soroban. [Pachi Pachi Land] 6 books (123456) and [Chibikko Soroban] 4 books (0123) cover the same range. In my home, the deciding factor was that it contained one-point advice, so I initially purchased Chibikko Soroban. However, with Chibikko Soroban: - The expected advice was mostly general things like "Sit in the correct posture" and "Praise them when they do well." - The paper was thin, so the text printed on the back could be seen through. - The space to write the answers was small, and the child felt stressed. Therefore, I switched to Pachi Pachi Land partway through. Pachi Pachi Land has illustrations and explanations of finger usage in the top 1/3 of the page, along with games like number mazes and number matching. The bottom 2/3 of the page has many problems, so the child could continue without getting bored. Also, for areas that take time to understand, such as the composition and decomposition of 10 and 5, the volume of problems is large, so it is recommended for those who want to practice repeatedly and those who want to steadily improve their skills with small steps. ● Will be shipped in an OPP bag + A4 brown envelope. ● Cardboard reinforcement is available for an additional 50 yen. #soroban #abacus #Nichiren #Zenshuren #mental arithmetic test #abacus test #soroban text #soroban problem book #Asahi Printsha Pachi Pachi 1-6 Answer Key
