And also how much it would cost?
I would like to do this as a project for me and my daughter.

Not fm. The discriminators in them are a lot trickier than AM.
You can get directions on AM crystal radios or kits for them pretty easy.

Try this site. It's Edmond Scientific's site and they have some am/fm kits and training courses.

Another site (Disvover this) has an FM only radio kit.

Truly building an FM radio from scratch will involve winding your own coils and building your own circuit boards etc. That's a bit much unless yo have a good background and some decent test equipment

You don't necessarily have to torture youself with a full fledged tuner and a discriminator, if your requirement is just "to learn how to do".
Look at this:

Circuit diagram, parts list, and only one transistor....!!
And no test equipment....
