Worksheets generators
Ishizaki training
Ishizaki training is one of the best soroban generatiors that I could find. Not only does it allow you to customize your own worksheets and
download them but also you can play speed games, have access to a virtual soroban and you can even practice math operations listening to the problems.
It's such an useful tool. I recommend you checking it out!
