I found this website called algebasics that completes Algebra problems in a step by step manner. Normally, I wouldn't put a site like this on my blog because the website does not have interactive resources. However, teachers could easily have students come up to the board and solve the problem and then show the video of the problem being solved. In addition, the problems can be stopped along the way allowing the facilitator to create more interaction along the way.
While the best use of SmartBoards is to have the students interact with the material, this site gives the teacher a number of options while showing the correct way to solve algebraic problems.
