What happened

Guess. Pour. Count. Explain.
You've watched it happen. Your child spends an afternoon building something — measuring, adjusting, arguing with the design. The next day you hand them a worksheet on the same topic and they're done in ten minutes, bored. A Quest is the building version, with a clear place to begin.

Quest

Start here
Find three containers. Guess which holds the most.
Bring back
A photo, a sketch, or what surprised you.

Worksheets have blanks to fill in. Your child does them to get them done, not to think. A Quest is different — it gives your child a real problem with room to choose how to solve it. The interesting part happens away from the screen, with real things.
Not feature lists. Real examples. Here's what happened when kids took these on.
