Observing the use of Promethean by a teacher

I presently attend a U.S. government class and a world history class every day to support my three freshmen ELL students who are in the classes.  Luckily, Mr. Butler, who teaches government, used a packaged Promethean lesson on the executive branch.  The presentation included information Mr. Butler had previously taught but it gave the students another opportunity to review for an upcoming test.  The presentation held their interest since it included questions they could answer, after which Mr. Butler would reveal the hidden answers by tapping on the board and students would see if they were correct.  The presentation was simple, short, and, as another tool for the class, worked well as a supplement.
