After our 3 day unit on Anne Frank and the Holocaust, I showed the students the website for the Anne Frank house in Amsterdam.  The site has a lot to offer with information and interactive activities like a virtual tour of the annex.  I wasn't able to show the students much during the day (because of time), so I wanted to post the link to the website for them to check out at home.  The link is found under the Useful Links section of the website.
