A forest floor covered end to end with muffins, animals wading through them

The Kidenomics Series · ages 4–7

Every book holds one big idea. None of them explain it.

Picture books about how the world actually works — scarcity, trade, incentives, and the reason a hundred muffins are worth less than one. Children watch, wonder, laugh, and work it out alongside Bunny and her friends.

The idea behind Book One

Bunny baked one muffin. The whole forest wanted it.

So Bunny baked more. Drag to see what happens to what a muffin is worth.

1 muffin
onea hundred

What'll you give me for it?

A shiny stone.

The muffin never changed. Only how many there were.

How the books work

The principle stays invisible. The story does not.

No lessons

No character explains anything. Bunny doesn't learn a moral — she works something out, and the reader gets there first. The economic terms appear only on the last page, addressed over the child's head to the adult reading aloud.

No villains

In Book Three, Bunny is paid a berry for every weed, so she starts planting weeds. She is never scolded and never sly. She did exactly what she was paid to do, and the book lets her be right about that.

No politics

Where economists genuinely disagree, the books stay out of it. One title ends with a shared meadow saved by a rule; another ends with private ownership working better. Both are in print, deliberately.

A message to parents

Every child is born curious. Long before economics appears in a classroom, children are already asking why we cannot have everything, why people trade, and why it is sometimes better to wait.

The Kidenomics Series began from a simple belief: the most important ideas can be introduced long before they are formally taught, and the best way to introduce them is through stories children genuinely love.

Each book holds one idea. Children are never told what to think. They watch, wonder, laugh, and work it out alongside Bunny and her friends.

If these books start a conversation at your dinner table, they have done their job.
