Three steps, and none of them is you sitting next to them.
Lay the worksheet on the table and take a photo. Creased paper, pencil, erased marks and teacher stamps are all fine.
The questions they got wrong go in first, and the answer they wrote becomes one of the choices, so they have to think it through rather than recognize a shape.
A game built for that worksheet. We play it through first, so we know they can finish it.
What changes when the correcting stops being your job.
We read the page: the printed problems, and the answers your child wrote in, wrong ones included. Then every answer is worked out again in code, so no machine's sums reach your child unchecked.
Problems they missed go into the game first, with their own wrong answer offered as one of the choices, so they have to think it through rather than recognize a shape. Then the game plays itself all the way to the end before you ever see it.
Getting one wrong costs a few seconds and nothing else. No lives, no game over, no red crosses. Your games stay private until you choose to share one.
The photo is deleted the moment it has been read. Not after thirty days. Straight away. We never store your child's name, and we never keep a record of which questions they got wrong. What's left is the game.
