I need a U.S. History Mission and a World History Mission

 I need U.S. History as a mission If I can get that this week that would be great! I work at an inner city school. I teach three classes of seniors at MERVO in Baltimore City. I am just getting in the class October 19th because the last teacher left and they had to find a replacement. I really found Khan's resources helpful and I would like to give my students a mission as they go on the winter break. I only have them two weeks after the break is over and I really need them to know this material when they finish the course. If there is any way you can help me with this I would appreciate it. I really want to see these kids do well and I need your help. This is a required course for them to graduate and really we have all worked really hard to get these kids this far. I want them to graduate on time but I need to know that they have this content before they do. Please help!!
