Eldest continues #soroban (Japanese abacus) 🧮 classes, including mental arithmetic #FlashAnzan techniques & regular drill practice on the computer…

This is currently a crazy physical and mental exercise where they run away from the computer, read the numbers to tally at a distance, then run back and type in answer 🤣

Apparently this helps maintain a small mental model in their (imaginary) field of view, leaving room for larger numbers in future. With some physical exercise as a bonus?
