Another source of ideas for things to do with the kids, are out of copyright old craft and activity books available online. They are often historically interesting and have great old fashioned illustrations i.e. more ideas for educational discussions if one is so inclined. In general Archive.org is a good place to find old books in various electronic formats. As is Project Gutenberg.
Here are a few:
A very cute drawing book
Home-made toys book
Paper cutting book
And there is loads more out there (some to be posted later:)).
