Children remember what they teach.

So we gave your child someone to teach. Their duck asks, they explain, it sticks.

Supported by

Your child teaches, their duck listens.

Your child picks something from this week's chapter and explains it out loud. Their duck does not know it yet, so it keeps asking why, and what if, until the explanation actually holds.

Ten minutes, no typing, nothing for you to grade.

Backed by science.

Rereading feels like studying, so most kids stop there. Explaining out loud is what exposes the gap, while there is still time to fix it.

Active recall, the Feynman technique, and the zone of proximal development: their duck keeps each question just beyond what a child can explain alone, then gives them enough support to get there.

Your child speaks without a script.

A new topic and 90 seconds to explain it out loud. It is the same kind of practice kids get in debate club, built into everyday homework.

Feedback on how they said it, not just what they knew.

You'll hear the difference.

Your child explaining something at dinner, unprompted, and getting it right. That is the part you'll notice first.

Questions, answered

That is exactly who we built this for. There is no class watching, no timer, and no wrong answer that costs anything. Most quiet children will talk to a duck long before they will raise a hand, and the duck waits as long as they need.
