Cinco de Mayo

The 4th grade team at my school does a big Cinco de Mayo rotation with all the students.  I'm planning a lesson for this afternoon on some Mexican folk art and thought I better remind myself why Cinco de Mayo is celebrated.  I thought it was to celebrate a victory and was just getting ready to search when I saw a video on Yahoo's Who Knew? News.  It's an interesting and quick reminder so I thought I would share!  Have a great day, everyone!
