If you are looking for resources, you’re in luck. There are many reliable sources producing good resources.
For working with primary sources, The WWII Museum in New Orleans has an excellent site. http://www.nationalww2museum.org/learn/education/for-teachers/primary-sources/pearl-harbor.html.
The folks at Teaching History have pulled together a nice set of lessons and resources, http://teachinghistory.org/teaching-materials/lesson-plan-reviews/25315.
Also the Discovery Education site has a library of lessons. This one is a good idea to have students do research and write. http://www.discoveryeducation.com/teachers/free-lesson-plans/pearl-harbor.cfm
