To start off with it is a good idea to get the kids started with easy Fimo clay ideas such as making leaf prints, magnets and more. It is also not necessary that the ideas has to be so "formal" let the kids loose with the Fimo clay and see what happens!
My little granddaughter jumped right in and started making tiny little plates, and mugs with the Fimo clay! Nothing elementary for her! True all were not an astounding success, but she had fun and all those little motor skills got some practice.
