We do a lot of speaking in schools locally.   Our favorite book for
youngsters is:
Our good OLD  "Sea Shells of the World" Golden Book by R. Tucker Abbott.

It shows the classes, the major families, the bivalves, the provinces
and a little bit on how to collect, clean and store.

I would say a good starter collection would be one of each of the major
families.
