If you want to create a digital portfolio for kids that will follow them throughout K-12, use these apps. In Evernote, create a collection and share it with the student. Then (s)he can add to the collection that will showcase their work. Gdrive for Google Drive is the best app to use as it connects your Google Docs to Evernote but for some reason it does not show here.
