Koko is built to ask, not to answer.
Its job is to make your child do the thinking — and you can read exactly how, right here.
Two deliberate exceptions: after two genuine tries Koko will model one step on a similar example and hand the problem back, and if your child is upset, hurt or asking about staying safe it answers plainly and points them to you. Koko is an AI model and can still get things wrong.

An example conversation
- Koko (example)
You have 1 pizza and 4 friends who all want the same amount. How would you cut it so nobody complains?
- Child (example)
Cut it into 4 bits. But my bit could be bigger because I'm the one cutting!
- Koko (example)
What would happen if the pieces were different sizes — would that be fair?
- Child (example)
Oh - no. They have to be the same size or someone gets less. So 4 equal pieces, and everyone takes one.
- Thinking move: proportion
- Koko (example)
You have that 1 piece from the pizza that was cut into 4 equal parts. What would you call your piece? Can you describe it using the numbers 1 and 4?
- Child (example)
A slice? I've got 1 piece and there were 4 of them...
- Koko (example)
The bottom number tells us something about the whole pizza — what does it tell us?
- Child (example)
The bottom one is how many equal pieces the whole pizza was cut into - 4. And the top one is how many I have - 1. So it's one quarter.
How we made this example
Koko's lines here are its own script, read straight out of the guided-derivation scaffold "Fractions from Fair Sharing" (strand Fractions, Stages 2-7) that Kocher AI gives Koko for this topic. In a real session Koko is given the same scaffold and puts it in its own words, so the wording your child sees will differ. The child's replies are written by us to show one typical path, and a real Koko waits for two or three tries before offering a hint -- here it offers one after a single try, to keep the example short.
