1. Play President Roosevelt's "Arsenal of Democracy" speech for the class, and have them follow along with the text, if you wish. Discuss what the phrase means (and add it to your unit vocabulary list). Have students make lists of the types of supplies and materiel that were needed to fight the war. What did people mean when they used the phrase "the war effort"?
The speech can be found here: http://www.americanrhetoric.com/speeches/fdrarsenalofdemocracy.html
2. Using computers, have students read a first-person account of working in the Philadelphia naval shipyard during the war, found here: http://explorepahistory.com/odocument.php?docId=1-4-191
Discuss both the conditions that people working in war industries experienced and how women and African-Americans gained access to factory jobs. Talk about how these new jobs changed peoples' lives, both by giving them income that they had never had, and by (in the case of many African-Americans) moving them to parts of the country away from the deep South. Add "Rosie the Riveter" to your vocabulary lists.
3. Have students read "Mexican-Americans and World War II" (a PDF can be downloaded here: http://hsp.org/sites/default/files/legacy_files/migrated/mexicanamericansandworldwarii.pdf). Point out the spread of Mexican-Americans to regions and states (i.e. Pennsylvania) where they had never existed in large numbers. Add "bracero" to your vocabulary list.
4. Use your computers to access a Warner Bros. propaganda cartoon here: http://www.youtube.com/watch?v=tEcJF0EVT54&list=PLBA9A0146C14188B8
Finish class by discussing the partnering of the federal government with multiple industries (like entertainment) to help win the war.
