Primary Shakespeare Company usually tour primary schools but this year are putting their resources online:-
once a fortnight the site has a new "book" about a new character here (specifically for special schools)
This page accesses the main resources. You need to sign up to access them but they are free
Youtube has a couple of videos on The Tempest.
This is a short animated version
This is a summary from "animated books"
Finally here is a song from BBC Teach which summarises the story
The BBC has a whole page of clips and resources for KS2 here. Having looked at the resource pack it will is intended for whole classes but could be adapted for use at home.
