Of course Black history should be taught as part of American history so that some day we will not have to have a special month. But until then, I have created two Intellitools lessons on the activities exchange for Intellitools Classroom Suites entitled Famous Black Americans and Famous Black Americans 2.
To download them you will need to open a free account and have the Classroom suites program already installed on your computer. There is a free trial CD/download for Classroom Suites 4 (http://www.intellitools.com/CS4_request_trial.aspx?site=itc)that will run the activities although they were authored with CRS3.
I hope you and your students enjoy them!
