A four- or five-year-old comes to understand what a quantity is by handling it. Ten dried beans split into two piles and pushed back together, again and again, is how ten stops being a word and becomes something the hand already knows. That is harder to arrange through a screen, and easy to set up on a kitchen table. The visit itself runs ninety minutes, built as several short, game-shaped stretches with a break in between, since a young child's attention only holds for a few minutes at a stretch.
- Objects the child can actually move
- A wrong digit caught the moment it lands on paper
- A parent can see the method and reuse it
